*With the caveat that the character will not be completely submerged in water.
If it says +3 spells, does that mean a total of 3, or only for a specific element? For example, can you learn 2 water spells and 4 electricity spells?
And, as Ples already asked, how does the unlimited magical power work with any healing spell (because in the end, it results in infinite healing), as well as with magical affinity (first, all energy is accumulated *80%, and then converted into health/???).
