From my research max stealth level should be +33.
Master of deception- 15
Night elf Racial- 5
Boots- 8 or 5
Cloak enchant- 5
5 stealth levels = 1 effective level of stealth, as in +30 being level 66 stealth on level 60 character.
How valuable are stealth levels when pickpocketing, let’s say Blackrock Depths where npcs are level 52-55? Is it worth rolling a night elf?
Escape Artist and Stoneform are far more powerful racials for a rogue. Still, I wouldn’t pick a race just for the racials. Pick what you like the most.
Stealth levels gives you more room for error and the ability to split some mobs(run between) that you wouldn’t normally be able to.
But that said you shouldn’t NEED the extra stealth to pickpocket BRD. It will just make it easier. Pick your race based on other factors, it doesn’t make that much of a difference to be the deciding factor imo.
