Rally

Back to Abilities Rally is a mechanic that is engaged whenever Kit takes damage. 40% of any damage (80% if the Griseus Special MK.II is in the players inventory) is also put into Rally which can be used to recover HP up to 200% of Max HP aslong as Rally-Enabled weapons are held when damaging enemies. You can even shoot with a Non-Rally weapon and switch to a Rally weapon to trigger the mechanic.
