World Tree. Astralym is Neutral-type with about 420,000 HP and one of the tankiest tower fights in the game. Weak to Dark attacks.
Endgame kit only: Legendary weapons, max-condensed Dark pals (Neutral takes bonus Dark damage), best armor you can craft. With ≈420k HP the 10-minute timer is the true boss — pre-buff with attack food, swap pals the moment one drops, and never stop firing.
