Toxic Beast

The Toxic Beast are similar construct creatures to their counterpart the Po Golems. However, rather than fecal matter making up their being, they are instead composed of organic, animated waste, slime, and radiation. Arguably more dangerous due to their increased size, damage, and use of status infliction when compared to their s***ty counterparts. In the case of the Toxic Beast it has two attacks; the first is a close ranged attack involving vomiting up several sacks of compressed goo, that after a few moments upon contacting a surface, explode into a massive wave of slime and toxins. This attack causes the slow condition similar to slime pools found in slime biomes. The other attack is swinging its arm and releasing a mid ranged orb of goo that sticks to a target and explodes shortly after for minor damage. The largest and most dangerous of the Pogolem variants, this creature is quite formidable due to it's slows and waves of damage it can release in short timeframes.

Toxic Beast is a unique monster found on any kind of _____ world. It is not capturable

Luna's Lab Notes
~ This monster is naturally uncapturable. However, if it strikes your fancy you can spawn a capturable one with the following admin command in game: /spawnmonster futoxicgolem 1 '{"capturable":true}.
 * (Upon further research and testing, I've found this creatures file seems to lack any input for being capturable or not, which is unlike almost every other monster file in the game. Interesting error and unfortunately causes this creature to die upon what would be a successful capture).
