As you guard enemy attacks with Gathering activated you will
gradually accumulate power. After accumulating a certain amount
of power a "Gathering Burst" can be triggered by using Gathering, damaging the surrounding enemies as well as causing additional effects such as reducing their speed.
When a character's HP falls to zero they will be temporarily downed and unable to fight. If Zael touches them while Gathering is activated they will be revived, with a short period of boosted stats. If a character is downed 5 times they will be completely knocked out, and cannot
be revived during that battle.
