Why are there spells which the caster cannot refresh ? While some spells can be re-cast while being in effect, some other spells cannot. If one tried to refresh them, a message pops up "This spell is already in effect". For example, that is what happens with Spellweaving's Gift of Life spell. Yet, there can be times when one might want to refresh it before it expires, rather than have to wait first for it to expire in order to be able to cast it again.
