Trinity Support
Supports skills that hit enemies, causing them to gain bonuses while you have resonance of all three elements, and to grant resonance of elements other than the highest one in a hit. There is a maximum of 50 Resonance for each Element. Cannot support triggered skills, instant skills, orb skills, brands, skills with a reservation, or skills used by totems, traps, or mines. Cannot modify the skills of minions.
How to think about it
This rewards hits that alternate which elemental damage type is highest. It needs a stable way to build and maintain all resonance; a tooltip showing multiple elements does not prove that cycle works.
What it can support
PoExplorer accepts a match only when this support's allowed types intersect the active skill's source types, none of its exclusions conflict, and any gem-only restriction is satisfied.

These are compatibility candidates—not a promise that every pairing is optimal for a particular build.
