Siphon Grenade

The Siphon Grenade is a grenade that leeches health away from enemies to replenish the thrower, first acquired in the level Lazarus Labs. It creates a short-duration dome-shaped field which deals damage-over-time to all enemies within it, with all such damage being transferred over as health. It is an equipment item, and recharges after use.

When combined with the Equipment Power Rune, the rate of health restoration is increased and the Siphon Grenade gains the ability to fill up the Slayer's armor once health is fully replenished. This makes it extremely valuable when combined with the Rich Get Richer Rune, and far more effective in combination with this Rune than using Armored Offensive.
