Hi Suzi,

You need to drag the fire goblin to a water source and that will kill it, You will also get some really good loot of it.

If you meet them underground then probably wall up the cave and run away for now.

Why purpose of spawning undestructible monsters underground with no chance to kill it ?

And keeping loss item when you die ?

I understand this monster can be in surface with chance to kill it with water, but underground it's just suicidal or very not fun.
