Like the above guy said, 7.5% of ALL damage taken is stored. That's what that red number is.

You also radiate energy to nearby enemies, and if any enemy is highlighted by your energy when Hysteria falls off, you take all of that stored damage.

If no enemy is highlighted when Hysteria falls, the stored damage fizzles out.
