You'll want to buy up magery skill to at least 25 or so from the npc mages so you won't fizzle as much when you use recall scrolls, but it is possible to survive without gm magery on a warrior. Plenty of vendors sell recall and mark scrolls so they are relatively cheap.
Magery provides alot utility spells, like recall. You need that to escape Player Killers. You dont need to GM magery. And you dont need any additional skills like evaluate intelligence. Not necessarily meditation and perhaps intelligence only up to around 40.
I have 25+ magery on all my dexxer/warrior builds. One great place to pull skill from to make room for the magery is tactics. If you run with 85 tactics, any magic weapon with +15 or more tactics covers all your skill lost in that area. 125 tactics is the same as 100 tactics so there is no reason to have GM tactics unless your using archery.
Aaaahhh ok i didnt know that 125 = 100 now i understand thanks (in all italian servers with the same magic weapons 125 =/ 100) Ok so 25 magery without medit is enought? only for reflect and recall scrolls right? Pls sorry for the newbie questions but this shard is very well structured and i need to figure out how i'll have to play when i'll leave occlo
