I beg to differ re: the Tourist. I think he's pretty well balanced and has a fairly straightforward skill progression. Very thematic and fun to play.
In the early game, I was mostly throwing things and using Persuasion for crowd control and to kill monsters. Had to be very careful about luring enemies out one by one.
Hunger was a real threat until I was able to get Iron Belly. Throughout Rogue setting, I was constantly forced to make decisions regarding which items to eat, which items to keep and which ones to throw as weapons.
However, once I sunk my first point into the Ambassador skill, that was all I relied on for damage and crowd control. By the time I upgraded it to 2 points, I was able to play the tourist as a mana-strapped summoner.
In the absence of a steady supply of mana potions (he's a terrible potion farmer), I had to run around and wait for my Energy to recharge. That's where Iron Belly came in.
Blend In works wonders to get out of tight situations in a pinch. Upgraded armor skill was essential for surviving Satan.
As far as damaging enemies, I like the Bowling Ball as a weapon, but found myself relying on stackable items. especially acid and poison arrows.
Bosses:
Genie – Easy to kill if you summon 1 ambassador at the right spot.
Pope – Position your ambassadors right and you'll be able to take down all four acolytes and bring down the shield completely. He dies quickly.
Satan – Not too bad. With two ambassadors, he can put a pretty consistent stream of damage, but has to re-summon as needed. Damage output is nowhere near the Fairy Wizard's Crystal Rain skill, but it's up there and it's consistent over time, so long as you don't run out of mana.
