This spell summons as much energy as the caster's body can stand, sometimes
even more.  This depends on how much spell points the character has upon the
casting.  If the spell should have given the caster more that 70 spell points
more than his normal maximum, these exess points can cause the caster to
catch fire.  The caster will be left in a very poor physical condition
after a casting of this spell, sometimes with some permanent effects, too.
