Goblin Spinecleaver
In the final battle against a group of goblins in the lost dwarven tomb, the party encountered one goblin who was noticeably more powerful than the rest. While the Goblin Cursespitter had spellcasting abilities, this one was large for a goblin. It stood over 5' tall and was powerfully muscled. It wielded a great axe. It took several rounds of concentrated attacks to bring the goblin down.
