Oopsie, sorry Moogle, and you see nothing magical about the blast in floor.
Missing, as I've said before, the heal skill is only usable for healing people with below zero health, curing poisons and diseases, and for healing hit points through long-term care (eight hours or more). This is the reason that clerics are supposed to use spells in order to heal players. If you want to use a spell then you may, but using the heal skill will do nothing unless you plan on staying there for more than eight hours.
