This is for conjurer:
Before joining the guild, train points in enchantment. get some points in air, water and fire as fast as you be able. if you are a halfling dont worry in training strn, if you are a humman dont worry in overtraining death. Do not over train whip, with a regular amount pluss guild bonnus you are able to kill almost any monster. Do not worry to train in FW till you think theres nothing more usefull you can put your skills in (im lvl 29 and so far i cant put skills in that). Train some points in meditation, lore, spirit and life. Look for high dodge equipment. Once you hit lvl 25, some points in spirit traveling could be usefull (i dont use them, but i know its a good skill). Acid recoil is your enemy, get acid protection rings. Use death protection ammy all time (unless you are a coward like mike that only killed nagas and undines). Blade spells, magic whip and resist spells are going to be your best friends.
Conjurer are master in pvm, but poor as pvp, also i think soon or later ranger and mages guild are going to be the reason of why the halfling are going to be nerfed.
I didnt want to put numbers cos i think you can do a little testing, but if you cant think for yourself and realy realy need another player set of skills, i cand send them in a pm.
