Cool Off (XC1)

Cool Off is 's in Xenoblade Chronicles. It is a lenghty process that eventually resets her rifle's heat to zero. If the gauge was allowed to fill completely, the art is used automatically, and it takes slightly over twice as long to complete.

Overview
Cool Off is Sharla's crippling weakness - no matter the circumstances, she must eventually take a time-out and leave the party unsupported to empty her talent gauge. Managing when exactly to do this is critical. Ideally, it should be during a time when the party doesn't need any support, or Sharla's arts are all used and she can't do anything anyways. In reality, it has to be used at inopportune times to avoid the time penalty from overheating, and since healing arts become weaker at high heat, if a lot of healing is needed it should be used even more often.

Notably, Cool Off is an aura. This means that any other auras Sharla has will be erased when Cool Off begins.

Additional data
While the aura is active:
 * Sharla drains 35% talent gauge per second normally, or 15% if overheated.
 * Sharla heals 3% of her max HP every second.
 * Sharla cannot move or act, and will skip chain attacks.

Cool Off may not be used during a chain attack; if Sharla reaches 100% talent gauge during a chain attack, she will drop down to 99% at the end of her turn.

Mechanically, when overheated, a different art is triggered (internally called "Overdrive"). It is identical in all ways except that it uses a different aura and does not have a chain attack type at all.

Note that the art's talent gauge value is 1%. Indeed, 1% of the gauge is lost immediately upon beginning the art. This is unlikely to make any practical difference.

Cool Off is composed of three states: beginning, loop, and end.
 * The timings in the above table are for the beginning state, which is when the aura is triggered.
 * The loop lasts for as long as necessary to vent all heat, and ends the moment the gauge becomes 0. If overheated, Sharla is immune to knockback during the loop.
 * The end lasts 120 frames (4 seconds) but can be cancelled into an art or auto-attack at any time.
