How to use this reference
This is a historical record from the May 12, 2026 Wiki dataset, not a Season 10 recommendation. The Holy Grail is classified as chance when casting. Check that activation condition against your actual skill setup before comparing its effect with another relic.
Compare the recorded effect and trigger chance below at matching levels. A damage figure is not a DPS estimate: the dataset does not establish cooldown, proc frequency, or current patch scaling. Test one relic change at a time with the same skill setup and difficulty.

Alternatives share an activation category, not a confirmed power ranking. Compare rows with the same recorded level; damage, healing, duration, and resource effects are different outcomes and cannot be ranked by their numbers alone.
