Trinity is usually known for her support roles but she can utilize extremely high ability strength along with Roar/Viral procs and Energy Vampire to instantly kill enemies all the way to the level cap. This is limited by certain enemies but we can still scale it all the way to the level cap in regular missions.
Roar is chosen because at this ability strength it allows you to instantly kill enemies without having to use Viral procs. Not every enemy is susceptible to status effects but they can be hit by Energy Vampire. [Rage] from Rest & [Rage] is another choice but requires more casting in some scenarios. Ensure that you have the correct primary emission color so that [Rage] is selected instead of Rest.
Link or Well of Life can be replaced. Their duration is so pitiful that they're nearly useless.
[Brief Respite] and the Augur Set mods allow us to prolong our shield gate while spamming Energy Vampire. With a Bleeding Dragon Key this gives us just enough shields to get a full gate for every cast.
Duration is intentionally lowered to near the minimum as Energy Leech sends out all 4 of it's waves almost instantly. [Fleeting Expertise] is rank 4 so that [Brief Respite] and the Augur mods will give you a full shield gate back with every cast if you have a Bleeding Dragon Key equipped. If you don't, simply make it rank 5.
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 needs to be higher than 326% to instantly kill enemies when boosted by Roar or a single Viral Proc but due to some weird rounding issues we increase it by a bit more to be safe.
Range is boosted a bit for Energy Vampire but it's mainly for the additional Augur mod.
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.
