Rationing

With this skill you will use half of an item and get its full effect. That could be with potions, poisons, food, water, arrows, and so forth. Any expendable item counts with this skill.

Potion Save

This skill allows you to quickly use a healing potion to cure your Vitality as you take a blow that would be greater than you can handle. Basically you will drink that potion as you take the hit, if the hit is less than your Vitality before the hit plus the potion, you will survive with whatever Vitality is left. Otherwise you will not survive.

Energy Trade

You can trade either Vitality, Power, or Soul with an ally for either Vitality, Power, or Soul as long as it is not the same stat. You trade at a 1 to 1 rate. Therefore you could trade 4 Power for 4 Soul and so forth.
