A Wicked Kataclysmic Confrontation


Black kats are once again storming the Moorcroft Manor Archives and consuming the precious tomes within! We need all knights of rank 4-1 and greater to gear up and retrieve Ancient Pages from these nefarious creatures.

Do the Kataclysmic Confrontation prestige mission and/or fight through kat levels in the Clockworks to find black kats. Then, visit Montague in Moorcroft Manor, or the Mysterious Crafting Machine in Haven, with your collection of Ancient Pages, to exchange for items:

  • Kat Claw hood, mask, cowl
  • Kat Hiss hood, mask, cowl
  • Kat Eye hood, mask, cowl

If you “accidentally” perform a Dark Ritual and survive the encounter, you may find yourself in possession of a Black Kat Cowl or a Wicked Whisker. Wicked Whiskers, dropped for all present party members, allow you to craft the following gear:
  • Kat Claw cloak, mail, raiment
  • Kat Hiss cloak, mail, raiment
  • Kat Eye cloak, mail, raiment
  • Black Kat cloak, mail, raiment, hood, mask
If you have participated in a previous Kataclysmic Confrontation and still have Ancient Page tokens, they are still valid! Ancient Page tokens do not expire.

  • New wicked colored accessories
  • Wicked Leafy Aura

Started good, then Sega touched it, sucked it dry, and barfed the husks up on Grey Havens. It went from an okay time waster to somewhere near RNG hell. Not worth playing, and is likely just on life support at this point.

Obviously, spoilers are shaded out. Mouse over them if you want to see them.

The spiral knights, a group of aliens running away from the Morai(an antagonistic group that next to nothing is known about) on their space ship called "Skylark", are shot down by a mysterious force, and the civilization crashes on the planet "Cradle." 4 spiral knights, known as the alpha squad, dived into the mantle of the planet before anyone else could, but mysteriously disapeared as they approached the center of the planet, being chased by the "living shadows". Beneath the surface of the planet are many worlds, natural and artificial. In some of these worlds, there are notes left by the alpha squad, regarding their journey through that area.

The core is a massive unnatural metal sphere at the center of the planet. It contains a massive amount of energy, but it's sealed off, with no known way to open it. At the end of the game, however, it is opened, and the "living shadows" are leeching off of its power.

The purpose of the Spiral knights is to rescue the Alpha Squad, wherever they are, and to exploit the infinite energy of the core to restore their spaceship.

At the beginning of the game, you create your knight. You can choose their eye color, eye shape, height, name, and armor(all the armors at the start have the same stats). After this you are shown the basic controls.

In the game itself, you are running through levels, defeating enemies with swords, bombs, and handguns, and protecting yourself with your helmet, armor, and shield. There is also select missions you can do to advance in the game's story.

Also, when you aren't running through the clockworks(the areas beneath the surface of the planet), you can talk with your fellow knights in haven, a town on the surface. There, you can also buy items from the "strangers", or other knights selling them in the Auction House.

The game's currency is called crowns. Every time you kill a monster, they drop crowns. You can also gain crowns by selling some of your stuff.

You can make your gear stronger several different ways. The main way is through heat, which also drops off defeated monsters. Another way is to craft up your item. The last way is through Unique Variants(commonly abbreviated UV). These have a random chance of being generated when you make an item, and apply a permanent random boost to that item. There can be 3 UVs on one piece of equipment.

As you venture in the clockworks, you can fight by yourself, or with up to 3 other people in most cases. The only exception to this rule is the gamemasters, who can join even when your party is full.

I love this game, but it has some SERIOUS drawbacks.
This is a great game, even though some aspects of it make me want to curl up and die.
Here is my list of pros and cons(don't worry, I'll explain these later).

  1. Gameplay
  2. Story
  3. Easy to play(mostly)
  4. "Extra" modes
  5. Nice first playthrough
  1. Gameplay
  2. Community
  3. Rarity
  4. "Extra" modes
  5. 2nd+ Playthroughs

For my pros, the gameplay is fun, especially if you like dungeon crawlers. I had never played a game like this before, and I loved it. The game is easy for new people to pick up, and you can make the game harder if you want to. The first time through the game is really fun, because unless you spoiled the story to yourself, the story is really deep and interesting. If you care nothing about Super-Endgame-Epic spoilers, read the hidden text following:The core is a prison designed by "The Architect"(presumably Tinkinzar) to contain the deity(the Sleeper) inside it, and to protect it from the ever-strengthening swarm(the "living shadows"), which it failed to do. The alpha squad is inside the core, fighting the swarm as it grows. The "Extra" modes, the Shadow Lairs, are freaky, fun, and offer awesome prizes...that is, if you can find actual good people to do them with, leading to my cons.

These cons can drive me NUTS, as much as I hate to say it. Yes, I listed "Gameplay" in both categories. The gameplay is fun in most cases, but the thing I hate the most about it has to do mostly with the weapons in the game. Some of the weapons are obviously superior for stupid reasons than other weapons in their same star catagory, like how the cutter series(this is the actual set of weapons I use in the game because its fun, poses a challenge, and actually requires a strategy to use) is pointless simply due to that half of their attacks don't hit (which is supposed to be this weapon's main selling point), and some people would venture further to say that it's awful because all of its lines do normal damage, which means it won't do tons against anything, but it won't do next-to-nothing against anything either.

Moving on to the community. I have met a group of GREAT people on this game that I hang out with alot. However, the majority of the game community is stuck up, because the people greater than other people refuse to teach the newbs how to get better, and only tell them what they mess up in. They also judge people for their weapon choices cause they didn't choose the statistically best weapon cause they don't want to feel too strong and make the game too easy, as in my case.

Becoming stronger in this game has been a pain since day one. My main problems come from all the types of rarity, for the same simple and annoying reasons. On crafting, the orbs are stupidly rare, and it's hard enough to get the specific type you are looking for. On forging, the problem mostly only applies to 5* items. The fire crystals are too rare, like before, and you need like 30 of the 5* ones to do anything with a large chance of failing, and if you can't find them, you're stuck with a weapon that is weaker than the one you had directly before it. Also, if your LUCKY, you might find 9 of those 30-90 fire crystals in ONE FSC run! YAY! SoLs are annoying also. Too rare, and too little benefit. The ones you get can literally be drained in one stratum, and the only benefit is the likely meh loot in that stratum.

I also mentioned the extra mode twice, once in each catagory. I hate it because it costs a ton to get in it, and unless you do it on the hardest possible setting, your stuck doing it yourself, while paying about 150,000 crowns to do it for the slight chance of getting epic gear at the end. AND, you will probably pay another 30,000 crowns to revive yourself.

Despite the monstrous costs, the most annoying part is the community again. As I stated before, most strong enough people won't join you unless you do it on elite, effectively slimming your chance of getting that gear your looking for. Even if you offer to let them in free on an easier difficulty level, they still mostly won't go with you. I know this from experience.

Another thing I found out is that playing the game more than once is boring, because of the cons listed beforehand.

All In All
I love this game, but be warned that their is significant downsides to the game.
The main way to overcome most of these issues is to get some nice friends to play with you, then spend the majority of the game working together. Or you can play by yourself and do what the stuck-up pros tell you to do: git gud(I HATE THAT).

Also, kinda off topic, but when people ask you for money, help them ACQUIRE it so they can gain battle experience. It'll keep you wealthy, and they will become smarter with the game's mechanics.

Storyline: 10/10
Unique and interesting.

Gameplay: 5/10
Fun for a while, but becomes monotonous.

I love the graphics. Why does the gaming community judge games they play by the graphics? That's also stuck-up.

OVERALL: 7.5/10

I really do love this game. The soundtrack is soft and arcade-like, the artistic design is *MWAH*, lore is nice and flexible, and the gameplay is simple and easy to get used to. If this was a couple of years ago, of COURSE I would reccomend this game!!

However, there are some big issues that suck the joy out of this kawaii child.
1. The economy, even in the early days, was nothing short of sucky. It's basically a 'im rich and have a few bundles of cash to burn' exclusive environment, making steady progression something more of an eternal endeavor.
3. omg u like lag? i like lag yes yes give me more lag
4. I swear this gets an update every X hours. I can never just OPEN THIS GAME AND PLAY IT.
5. Community jumped ship because they were smart.

I love this kid. I want to see it grow up happy and healthy. I'd only recommend playing it if you feel D E T E R M I N E D enough. Otherwise, it's not worth your time.

It's a very fun and long game once you accept how it suddenly became Spiral Fortress 2 with the accessories and unboxing several dozen different collections of colored boxes that contain re-colored variations of said accessories that they have been peppering the game with instead of new dungeons, enemies, weapons, and equipment that can actually be acquired through enough work and not just purely by whipping out the magic credit card.

Things were a lot simpler during the Mist Energy era.

I would recommend this game to anyone. This game overall is an absolutely delightful experience. It has a beautifully simplistic style and the music is flat out awesome (seriously. I would buy this game with money if it were just a blank screen with a quit button and the full soundtrack playing on repeat). I'm gonna be honest, I got into this game purely for the tf2 hat, but found myself completely lured in by it's extremely charming auditory and visual style, as well as it's strangely addictive gameplay. I was very suprised when I, first thinking that the simple hack and slash fighting style would get repetitive fast, discovered that... it never really did. I also like when you can customise your character's appearance and for some reason they just end up looking completely badass. One thing that I disliked, however, were the Candlestick Keep levels. I hate to be rushed, especially in such a pretty game as this one. What I'm trying to say is that this game is awesome, and I have no clue why it's free.

The game was great a few years back it really felt like a zelda link to the past dungeon like game, then it turned into PVP bomberman series and the energy limit cash grab made it so you can only play it a few hours a day, after all these updates the game has expanded but died off and made the game worse. Rip what this game could have been.
Still if you havent played it grab a pal and run some and then never comeback I guess
