Osamodas/Vitality/1

This build stresses staying alive and relying on your summons. It's less interactive than one with more intelligence, but you can also make up for intelligence with items.

Generally stick all of your character points in vitality so you stay alive in battles and level your summons with your spell bonuses. Also, try to find any of the items that let you summon multiple creatures (like the goball hammer) to really be good. once you have tofu spell lvl 5 and can summon 2 at once, you should be decently well set when you upgrade your goball spell.

The problem with this build is you completely rely on your summons. You generally cannot defend yourself at all, even when needed. This does allow you to go against higher level melee classes than normal (goballs, boars, etc.) but anything that uses ranged attacks will be harder to defeat because you don't get a summon with a ranged attack until level 17.
