When it comes to hide, sneaking I think of 3 classes:
- rogue assassin
- monk ninja spy
- ranger deepwood stalker
a combination of 2 of those would probably work well.
Monk offers much however in order to work well it needs many monk levels
assassin and deepwood stalker seem to be 2 sides of the same coin, both have "killer", idk if they stack.
an assassin wears light armor, a monk wears.. robes
Races
- halfling
comes to mind
The idea is, evade fights, sneak - and quickly - through dungeons. But have kaboom for bosses.
Weapon Kukri, assassin and ninja would work well but in robes so spike dodge
The question is, have 2 rogue levels and 12 ranger 6 monk, or 12 monk 6 ranger?
11 levels of ranger = greater twf
6 ranger = improved twf
9 monk = improved evasion
13 monk = diamond soul
That's all I've got for now, tired
