[Wick]

I was going to say that while a Bane Spider costs twice what he should at least his stealth was fixed, but I see that relatively it wasn't.

Edi, here's a clump of DB fixes (this is easy if you sort by the assassin column first):
443 Star Child is listed as Stealth 5, is actually 15.
585 Guild Master is listed as Stealth 5, is actually 25.
629 Stalker is listed as Stealth 20, is actually 40.
877 Bane Spider is listed as Stealth 5, is actually 10.
1436 Mujina is listed as Stealth 10, is actually 30.
1558 Tlahuelpuchi is listed as Stealth 0, is actually 15.
1744 Samanishada is listed as Stealth 10, is actually 20.
1879 Serpent Assassin is listed as Stealth 5, is actually 20.

Bug:
863 Apostatic Warrior really is stealth 0, probably should be 15 or 20 if he's an "able assassin".
