Hello I recently started a troll and have died a couple of times, but the only real penalty I saw was it took me back to the refugee camp. I tried searching the net but didn't find anything. Does anybody know if you lose gold / experience?

On "normal" difficulty, you just pushed back to the town. (You only loose time.)

But on "difficult" and above, you die and spawn at town without your gear. You have to run back to where you died and click a tombstone to get your items back (they're not auto-equipped, either). One of the problems is the enemies don't really move from where they killed you. So you just die again and again trying to get your gear back.

But after doing finishing the Lilitip's Chest quest (he is a Goblin in the Swamp Camp), you can pay for Lilitip in any given town a small insurance fee and if your character were to die, you'll revive in town with all your gear.
(The fee is higher with every death)

Nice to know! I had run across him on normal difficulty but it didn't let me purchase his "insurance" so I figured maybe it was a joke :)
