With Mystic Charge, the mystic can charge the air around himself with a mystic effect for later use. He must announce the purpose of the effect at the time of charging (though he need not specify the target of the effect until the time of release). He can ward the charge (see the Warding section) to prevent the charge from decreasing by one point per round in each sphere. The mystic can release the charged effect as a free action (ending the warding, if any), resulting in multiple effects in a single round whose combined sphere total exceeds his usual limit. If the effect being released is of temporary duration, the mystic can choose to ward it normally at the time of release.
For example, Hobbes the mystic cleric, in a fit of pique, decides that he is going to have a lot of fun with Displacement at others’ expense (see the Displacement section). While talking to a group of pointy-hatted gnome triplets, he charges up Dis 6 to send the first gnome to designated location A for 2d6 rounds. On round two, he charges Dis 4, to send the same gnome to a second designated point B for 1 round, and wards that as well. The next two rounds he repeats this process with the second gnome, setting location A the third round and another location C on the next. He also wards both of these charges. On rounds five and six, he does the same for the third gnome, setting locations A and D respectively. Naturally, these charges are warded too.
On round seven, Hobbes releases each effect in order, causing each of the gnomes to go first to location A and then to B, C or D. Knowing that he has way more HP than any of the gnomes, he steps into location A just before the displaces to locations B, C and D wear off. Each round thereafter, each gnome snaps back to location A (since those displacements are still in effect), causing 6d6 damage to each gnome and 18d6 damage to Hobbes (6d6 per gnome). Since an obstacle is blocking the replacement, the gnomes cannot leave locations B, C and D, and this cycle of pain and hurt repeats every round until Hobbes bores of the process and steps away from location A (or until the remaining displacements come to an end, or Hobbes dispels them manually).
From this example, we conclude that Hobbes is a sadistic bastard, and that three gnomes are in a world of hurt.
