Today I discovered that some people can solo orcs! Or as you can see in the picture below, at least one person can solo orcs!
We followed Illia the orc-killer into the cave.
This is Ouric the orc-boss.
She has a freaking pile of potions in a stash! My god... (We wern't allowed to touch them)
Finally I got the see the orc alchemists, who drop the alchemist belt, and apparently pass potions to wounded orcs to heal them.
I suppose I've seen all the game now. I even got to escape the cave alive.
