Keeping an eye on your health during battle is paramount, so it's best to know if you can heal or not without clicking...
When your health is above 50% you can't heal, don't waste a click and just see whether the [HEAL] [POWER HEAL] is in italics or not.
Can't heal =
[HEAL] [POWER HEAL]
Can heal = [HEAL] [POWER HEAL]
