Depends on what type of mage you want? for pvm or pvp or both? tamer/mage? tank mage? etc
if it is a bog standard mage I would suggest things like:-
magery (as thats what you are, hehe)
eval intell (for damage increase)
Necro (works well with mage spells)
inscription (adds bonus to some spells and good way to make money and fill spell book)
med (but only if you can't afford or find nice suits with high Mana Regen etc)
wrestling (to try and help stop spell fizzle in combat)
mace fighting (same as wrestling but handy for things like the boomstick for its high lrc and still stop spell fizzle in combat)
poisoning (to increase level of poison/poison field)
Spirit speak (to go with necro/mage combo, and can heal u)
my mage is a mage/Necro/tamer, so i have:- magery, eval intel, taming, lore, vet, Spirit Speak and of course necro
his stats are :- Str 100 Dex 40 Intel 110
