Certain abilities types might have a recharge attached to them. They are typically tied to Attack abilities or certain Class abilities. (This was mostly tied to monster abilities in other game designs.)
Only while in combat are these abilities depleted, and charges are reduced.
At the start of the Caster's Turn, a Recharge Ability Roll is made, on a , an the Roll Result has to be lower than the beginning recharge Range.
Example:
Lightning Hands has a recharge of 5+ on a . If this charge is depleted the Caster rolls a on the start of the Caster's Turn, and if the Caster rolls higher than a 5, the Ability is reset on the start of the Caster's Turn.
