my tip is be a s/s int with 90 light 90 cold 90 sword 30 fire.
Ive not been beaten by any warrior or warior cleric.
..and be clever dont go into the fight with snow up wait untill the last possible moment to use it. Start with ironwall as soon as they bring the 2 handed sword out then when thats gone stick snow up they shuld have around 20-30 secs of bless left at that point. when that goes they will prob use there skins if not already by time there gone u still have over a minute of snow left, more than enough time to rape them.
If they then switch back to cleric to stop u killing them then thats fine they cant kill you while in cleric mode watch for that sneaky change back to 2 handed sword and have ironwall ready.
of course this only works if u got sword skills
