Tale of Diep:Last Warden of the Tower

The Last Warden of the Tower is a Gladiator Boss that has a 5% chance of replacing a Defender spawn. Created by ZathusTheMageV.

Design
The Last Warden of the Tower is a giant light gray Fallen octagon. It has a two-sided Dominator Auto Turret on top and a Trapper Auto Turret at each corner. On each face, Spawners and Destroyer Auto Turrets alternate. There are rectangular metal grates on the top. The Auto Turret thing on top actually has a giant red eye like The Saw or The Octagon. This makes it like a much more powerful version of the latter.

Backstory
Upon discovery of the Tower of Gladii, the Archprophet knew he needed an elite force to defend it other than himself. As such, from the strongest of his ranks, he recruited the Wardens, five masterful cultist warriors. But... they all died in past conflicts. And this one... is the last.

Special
Should the Last Warden of the Tower be killed in any Diep.io server, Fortress Mode has a 10% chance to spawn the next day regardless if it shouldn't. Because Fortress Mode is an Event Gamemode that only spawns every other Thursday, killing the Last Warden of the Tower can change that. This effect will not stack, so subsequent Warden kills will not boost the percentage if it would already happen.

Attacks
Note: Even while an attack is not happening, it is passively slowly sending out drones and firing bullets from all its turrets at players
 * Cataclysm: Its twin-sided Dominator Turret will slowly spin and rapidly fire four streams of Gunner bullets each. This can last anywhere from 3 seconds, to 8 seconds.
 * Unleash: Each spawner will begin releasing ten Fallen Overlord Crashers a second for 5 seconds. Two seconds after the ability ends, any remaining Crashers get Speedy.
 * Powerball: Each of its side Destroyer barrels will release an Annihilator bullet that will begin rotating around the Last Warden for 3 seconds at a very fast speed, before firing straight outward.
 * Fortuity: One random player will be selected. A fast bullet that does almost no damage will be fired at them. However, they will get Slowed and Broken for 4 seconds.
 * Metal Skin: Will get Armored for 8 seconds and fire punches of powerful shots from its Destroyer turrets.
 * Bloodjack: All spawners and side turrets will retract. A giant thin lance will come out of all eight sides, and the Last Warden will begin spinning rapidly while having Speedy.
 * By Thy Honor: The eye's pupil will fire a rapid stream of bullets in a laser, sweeping a 60 degree angle area.
 * Hell's Gates: Tears of Panzer will begin warping in from around him in black flashes.
 * Fireball Storm: Spell taken from the Archprophet. Eight orange bullets will rotate around the center eye, and fire outward in circle formation at a player, before boomeranging back in a straight line. This attack is used three to five times in repetition.

Trivia

 * This is the third appearance of the ability 'Fireball Storm'. The other two to have this attack are the Archprophet and the Archpuppet.
 * The other four Wardens aren't important.
 * The design was made in Graviatar style, but the mechanics themselves stay the same with my stuff.
