After winning my first Yeek (a Summoner) and enslaving the whole world with "the Way", i have been toying with Halfling Rogue and was surprised how horribly bad they were in early game.
I lost a lot of them
Then after leveling one that got lucky enough to get decent gear early, and getting the stealth finally decent (first few skills level being as good as not having it with the other skills from the stealth line) and so every action not removing it anymore, the character become surprisingly powerfull, with stealth and hide from plain sight on autocast (and the talent that prevent actions to remove stealth), it's critical hits heaven, with tons of bonuses in the Pride my character managed while using Flurry to get 2000 damages against some of the enemies not specifically protected against my type of damage !
Though he's far from invulnerable, i took "Lucky Day" prodigy and wear some +luck items to help getting more than 100% evasion for 3 turns when losing 10 % health from the Halfling racial ability , but it looks like despite it is at 102% , it does not stop any aoe damage and sometime i even noticed that normal melee attacks are not evaded at all !
It seems sometime it works as it should, but some other times it's like it's not there (despite listed if you look at your character)
Additionally, every single monster of the game is able to "briefly catch sight of you" , regardless on how high your stealth power is (i'm currently at more than 90 and still get the message everytime, the same as when i had much less stealth power).
Fortunately it does not mean they know where you are -exactly- as they don't all shoot you on sight, but they still move to you for melee, fortunately again you still benefit from not being seen regarding the hit bonuses of your skills and weapons.
The fun with Rogues is when you have high Misdirection, it's hilarious when they miss you when shooting their spells/abilities and hit someone else
