Sneak to drizzt area and wait for him to die (free lewtz; I know lame
Carnival area, kill thief for potion of master thievery
Cloak of protection +1 west of Ulgoths beard in the house
Ulgoth beard steal Dushai's ring and draft kneecapper (helping killing those peksy flesh golems). Also bastard sword +1 here.
Beregost at night for another bastard sword +1
Pickpocket Algernon's cloak from beregost inn.
Nashkel for ankheg armor.
Note I ommited stuff that's nice but not really helpful at start like wand of summoning (few charges and no money to recharge so better save it), ring of fire res, scrolls etc. or things that require effort to kill. This is pretty much no kill route.
If you bother with easy kills go for
marianne husband ring of prot +1 for killing two ogrillons
south of Friendly Amn Inn Gridle of piercing from orge
Shoal for nice helmet
At this point I'm pretty beefy so I go anghekgs, shoal etc.
Did I miss anything that's particulary free but worthwhile?
