[Trinity] is a great general support frame but we can [Sacrifice] some of her defensive tools to make Energy Leech the best energy restoring ability in the game. We subsume an additional support ability that fits with the minimum duration.

Fire Blast is chosen because it cripples armor without needing duration. Empower allows you to boost the strength of Energy Vampire in the downtime between waves so you make the most use out of a single enemy. Pull can bring energy orbs dropped from enemies towards yourself to proc your own Arcane Energize near your teammates.

Link or Well of Life can be replaced. Their duration is so pitiful that they're nearly useless.

[Enemy Radar] mods help you and your team to find enemies. The nature of this build sometimes forces you to track down stragglers.

Duration is intentionally lowered to the minimum as Energy Leech sends out all 4 of it's waves almost instantly.

Efficiency doesn't need to be any higher than 100% as Energy Vampire will give you all of your energy back anyway but [Fleeting Expertise] needs to be run anyway to lower the duration.

Strength doesn't need to be any higher than 125% for a max Blessing heal. It won't last for very long but at least you can fully heal your allies.

Range is boosted for Link and Energy Vampire even if it does nothing for Blessing. This grants you greater freedom to separate yourself from you team.

[Vampire Leech] is a great augment that grants your entire team constant shield gating.

Arcane Aegis combines with your shield gating to make you nearly invincible. If you don't like the RNG or don't need more survivability you can replace it with Arcane Resistance to deal with infested or enemies with toxin damage.
