This spell allows any item you're holding to be absorbed into your body. The item must be less than 20% your weight. Two of its dimensions (width, heighth and depth) must be no greater than ½ your height, with the remaining dimension less than twice your height. The item remains absorbed until you decide to harmlessly expell it (a standard action).
After one hour, whenever you take damage of any sort, you have to make a will save vs. DC 6. But for each hour the item remains absorbed beyond the first, you gain a cumulative -2 penalty to this roll. (After three hours, the penalty is -4, and after seven it is -12, for example.) If a save is failed, or if you fall unconcious, the item is forcefully expelled. This causes you to suffer 2d4 damage.
You radiate faint transmutation magic while holding the item. A successful dispel magic cast on you causes the item to be forcefully expelled.
You may absorb multiple items (through extra uses of this spell), so long as the combined mass of the items does not exceed 20% of your weight.
Material component: A dry sponge.
