Focus 120

Focus is the easiest skill to train, even if you don’t want to. Every time you regenerate 1 Mana or Stamina you have a chance to gain in Focus. Thus, simply do activities which cause you to lose mana and stamina. Using up mana can be accomplished by casting any type of spell. To lower stamina you can just run around a lot. Doing both at the same time will quicken gains. The Necromancy spell Pain Spike would be especially useful.

It is best to train Focus last because chances are it will be close to 100 by the time you focus on it.

Since a warrior’s swing rate is determined by the amount of stamina he has, the ability to increase the regeneration of that attribute would be highly beneficial on the battlefield. Mana, too, is an important stat to any warrior that uses special combat moves as part of his tactics.
