Grey Prince Zote

Behaviour
Frantically swings his nail while following the player before slamming down, creating two medium-sized shockwaves.

Inflates his stomach before spitting out two bugs, either Winged Zotelings or Hopping Zotelings.

Vanishes into shadows before reappearing above the player, slamming the ground, creating a shockwave in two directions.

Leaps forward, slamming the ground and slashing his nail, creating one small shockwave behind him, and one large shockwave in front of him.

Attempts to slash but falls to the ground, creating two shockwaves.

Jumps backwards, creating two tall shockwaves.

Raises his nail in the air, creating three Volatile Zotelings.

Tactics
Gives no chance to heal without Quick Focus and Baldur Shell, even then, it's likely he'll break the shell.

For damage output, Nail-based Charms work very well; Fragile Strength, Quick Slash and Mark of Pride/Longnail help immensely.

Shade Cloak and Monarch Wings are useful for avoiding his shockwaves and Volatile Zotelings.

He can be fought infinite amount of times, but each time he will deal an +1 damage, e.g. first time fought, he deals 1 mask of damage, second time 2 masks of damage, etc.

Location
Fought by Dream Nailing his statue in Bretta's Basement.
