The Immortal/Level 3

In this level, a slew of trolls, who are at war with the goblins, who can be evaded using a handful of handy items such as smoke bombs. Here, the Protean ring, which causes the character to be disguised as a goblin, can be found. Be sure to not wear the ring in front of the Goblin King, as he will see through your disguise (and as you should know by now, mistakes are usually fatal in this game).
