GLASS MANTIS
This boss is a very colorful Mantis and it has wings, those are the main differences. It will fly around then land on the ground acting as a hybrid, and even freeze you with its attacks. It’s also bigger and when you "k1ll it", the head will pop off and it’ll go into a berserk mode, by the way, mantises can survive a long time without a head because of how they breath(like a c0ckroach).
When you k1ll the boss, it’ll drop Glass Chunks for making glass and weapons. They’ll also drop Glass Wings used for a hang glider, or Glass Arrows (1 Glass Chunk, and 3 Glass Wings for 20 Glass arrows). Glass arrows deal 38 smash/stab damage. The Glass Mantis will also drop a Glass Mantis Head for a Glass Mantis Statue, or for a Kaleidoscope trinket that makes you stun ORC enemies, and deal 50 fresh damage with normal attacks, 500 with charged attacks.
The boss will spawn underground in a little "cavern" with geodes. The geodes glow and when you break them they’ll drop crystal shards for things like flash bangs. Also glass versions of other bugs live here.
