I don’t play Trinity much because I have a natural aversion to buff jugglers (same problem with Gauss), but, she has some cool stuff in her kit that does make her quite fun to play.
First up, Vampire Leech combined with Nourish gives her excellent shield gating ability, for the whole squad, as overfilled energy will spill into shields. EV builds also have a purpose again with this strat. Very powerful. Energy Leech in general is very fun for new players who are still getting their energy economy toolkit filled out. The whole squad will benefit from at least 6000 shields and very high shield generation, and Trinity herself goes up to at least 24k. That’s a lot of shields.
Instead of running Nourish/Vampiric Leech, Pool of Life lets you build Trinity as a chonky health tank before you ever need to think about Helminth. Only problem is it’s slightly clunky, especially if you’re pumping her duration to make her less spammy: it requires manual deactivation, while also trying to ensure the enemy has taken lethal damage while acting as a Well.
Link has the very nice property that it bestows status immunity, including knockdown immunity. If your crowd clear is too good though, say goodbye to your link and get ready for the self-stagger. This is less of an issue on Steel Path, but still a major bugbear with the ability due to how the status immunity behaves when Link swaps to a new target.
Blessing is the classic, of course. While it was nerfed some time ago to be basically useless for objective healing, being able to project damage reduction to the whole party and quadruple their EHP is quite nice. Plus the healing. If you bring a supply of Ancient Healers it’s also possible to have a reliable “battery” for Champion’s Blessing. If you’re running Nourish this actually gives Trinity quite a good damage potential.
The passive is nice too, especially if you’re running Vazarin and potentially even Amalgalm Shotgun Barrage.
Overall she’s really good, and actually carried me a long way when I was still new, back in like 2016 or something. I mentioned in my other thread that her pace of play needs some tweaking. There’s too much juggling and her casts are glacial. If you don’t mind that though there’s an absolute beast of a frame in there.
She also has a cool lobster tail dress on her Prime, so that rules. Trinity best lobster girl.
Edit:
I’ll try and get a video up eventually with the specific Tankity builds I run. Can’t recommend Vampire Chef Trinity enough.
Also worth noting that Energy Leech bestows all remaining ticks when the marked target dies, so it’s compatible with high duration builds.
