The Aberration

Info
The third boss of the game. Used to be the last one until the Forgotten Crypts update. Quite hard to defeat. Has a lot of lore behind it, you can read it at the end of the page, spoiler alert!

Fight
The Aberration has 2 kinds of attacks:

The Ball of Doom
The aberration shoots a ball that splits in 6 pieces when hits something. If the player shoots at the said ball, its pieces will move much faster than when they hit a wall. The Aberration spams this attack filling the room with small balls. It's recommended to equip Freezing Bomb and freeze the Aberration as much possible so you wouldn't get hurt.

The Tentacle Strike
The Aberration tries to hit the player with a row of small tentacles coming directly from it to the player. You should circle around the boss to evade it.

Tentacle Walls
The Aberration will create walls around the player to restrict their movement.

Lore
SPOILERS AHEAD!!!

The Aberration is actually the creator of the dungeon, therefore the location name The Architect's Lair, a half-elf who made effort to show the people that mana can run through humans. He knew that people wouldn't believe him if he told that human can make magic because he is only partially human, this is why he conducted human mana body experiments, to see if humans can get mana, for they are the only species in this world who are born without it. Half-elf is also the author of books you can find in the dungeon.
