Backstory:
In the deepest part of Candlestick Keep, known as the Candlestick Sanctum, a Greaver has reached an immense size as a result of feeding off the residual magical energies found in the keep. The Spiral Order has decided to send Knights into the Sanctum to take this creature down before it chooses to head upwards to feed off of Haven. Greavstriken himself resembles a giant Greaver with glowing gold runes/marks all over him
Levels:
His boss levels are similar to regular Candlestick Keep levels, but have fewer Grimalkin and added Greavers.
Depth 24: Sanctum Perimeter
Depth 25: *
Depth 26: Test Subject Containment (Has a more varied range of enemies, such as Beasts & Slimes)
Depth 27: Sanctum of Knowledge (Has more of a "Library" feel.)
Depth 28: Summoning Chamber (Boss level)
The arena where you fight Greavstriken has a Candle in each corner surrounded by respawning breakable blocks. In the center of the room is a large pedestal with a respawning fire ball on top, to one of the sides is a switch that when hit raises the pedestal into the air. The candles do not go out unless he puts them out (see "Boss Fight")
Boss Fight:
For every candle that is not lit Greavstriken takes 25% less damage (so he is invincible if none are lit.)
Phase 1:
Greavstriken has the following attacks during this Phase:
Dark Cyclone (beats his wings back and forth rapidly, this puts out the candles, knocks back nearby Knights and sends out several bullets in all directions)
Eye Beam (sends out three Retrode/Brandish style beams in a <- (like a birds foot without the back) shape)
Charge (self-explanatory)
Phase 2:
After being sufficiently injured Greavstriken flies high into the air, where he cannot be hit. While airborne he has the following attacks:
Swoop (a purple line appears along the ground and a second later he dives across it, dealing heavy damage to anyone in his way.)
Shadow Bomb (calls down several little AoE shadow balls, kinda like the Roarmulus Missile attack.)
The players must try and get him to Swoop over the pedestal, then flip the switch to raise it before he goes over so he crashes into it and gets knocked out, allowing the players to attack him for a bit (he won't swoop towards it if it is already raised.)
Phase 3:
Similar to Phase 1. Greavstriken now glows red instead of Gold
Dark Cyclone now sends out more bullets
The Eye Beam explosions now send out bullets
Charge now leaves a DoT AoE in its wake (like a regular Greaver)
Greavstriken can still use the Shadow Bomb move
Phase 4:
Similar to Phase 2. Greavstriken summons some Greavers when this wave begins (non-respawning) and his body now appears cracked.
The switch for the pedestal is now covered in a force-field.
Greavstriken sends out a trail of bullets to either side of him while Swooping
Shadow Bomb now sends out bullets when it explodes
Greavstriken has a new attack for this phase:
He flies to the center of the room, hovering over the pedestal and projects a single beam (Ironclaw Factory style) from his eye and slowly begins to turn, while constantly sending out bullets in all directions. He does this until he has done a complete 360, whereupon he stops and lowers the force-field protecting the switch. The players then hit the switch which causes the pedestal to raise upwards and set him on fire, whereupon he Swoops away. This must be done several times.
Phase 5 (Final Phase):
Similar to Phase 3. Greavstriken now glows pure white and the cracks are worse, with tendrils of energy coming out them. Both switch and pedestal are now broken.
Greavstriken now summons more Greavers and will now re-spawn them infrequently.
Dark Cyclone no long extinguishes the candles and shoots slightly fewer bullets, but now the bullets explode into more.
Shadow Bombs now leaving a damaging mist (similar to Haze bombs)
Charge now sends out a spread of bullets when it ends.
Greavstriken may fly away and Swoop a few times every now and again.
Greavstriken may still use his "Beam 360" move, but no longer has to pause after doing so.
Items:
The tokens are called "Greaver Gems" and are described as "Gems that glow with an unusual energy, taken from Greavstriken as proof of your victory."
The items that can be bough with these tokens (25 tokens each) are:
Greaver Gem Shield (4-star):
A Shield modeled in the shape of a Greaver that has Normal & Shadow Defense and has a Low Handgun Damage Bonus. The 5-star version (Greavstriken's Visage) has a Medium bonus and is modeled in the shape of Greavstriken himself (as he appeared in Phase 5.)
4-star Description: "The enchanted eye on this shield can be seen through by the user, granting them an unnaturally good aim."
5-star Description: "If the Malevolent gaze of this shield does not give you pause for thought then perhaps the hail of bullets from its user shall."
Void Shard Launcher (5-star Gun):
A gun resembling a crossbow. The regular fire shoots about 6 shards of crystal like a shotgun, the Charge attack fires a single larger crystal that can penetrate multiple enemies (and can Bypass the shield of a Trojan)
Description: "The shards of Crystal launched by this device seem to be slightly out of sync with the rest of reality. "
Ruinous Crystal (5-star Bomb):
When detonated it sends tendrils down into the ground below that come up as dozens of spikes that deal shadow damage to anything in it's AoE (similar to the Lichen Colony's Spike attack) Average damage but very little knockback.
Description: "A Crystal that seems to be reaching out, as if trying to grasp and consume everything around it."
TL:DR: Idea for a Greaver boss (and why are you on a text-based forum if you don't want to read?)
Just a little thing from me and does not reflect on the validity of the suggestion;
Greavers haven't been associated with the Keeps- Perhaps a Kat boss would fit better.

On the Suggestion;
1st off, the token prizes are very nice, perhaps add a nice Gunslinger set to match with the shield. And WONDERFUL idea for an AOE shadow bomb, we need one so desperately! But 25 tokens apiece seems a bit... low. Vana's prizes are 30 and up.
Needless to say, though, personally I would hate this stratum so very much, as Greavers and Keeps are my two biggest gripes with the clockworks- not from difficulty, but from just being annoying.
Nevertheless, Well thought out suggestion, Though I think it would be nice for a tier 1 or 2 boss, to give some early gunner gear, but that's just me.
I can only Imagine the rage that will come from a team up of Greavers and Grimalkins... mweheheh...
