with stamina, if you get hit by someone with a fat mace, then your stamina will drop and then your characters swing speed will drop. If you have a free hand then you can chug refresh pots so then its not really a problem. by focus is always nice, for mana regen too. id go with gm poison (100) because i think thats the only way that you can lethal poison... I know my mate garrick has 100 poison and he does lethal where as a mate at 90 doesnt. Id drop parry and go for a free hand.

The char im thinking of making is a alchemy poisoner, so you get the boost on drinking pots and i can throw explosion pots. not sure if it will work but it will be fun.

I like swords for poisoning, but i think im on my own with that. i like the cleaver for the bleed and poison combo, and i like the butchers knife for the disarm poison combo. pretty nasty! but thats up to you....

so id go...

120 swords/fencing
120 tactics
120 anatomy
120 healing
100 poisoning

then you have 120 free for whatever you like, you could go with ss for the extra heal which heals through anything. im a ss fan! or focus/med for the regen.... parry if you wanted to go with the shield and u could set up macros for dropping the shield and chugging a pot. or spell resist to avoid nasty curses, para and mana vamp, but for a warrior i wouldnt suggest it as theres ways round it...

good luck mate
