Innervating Locket enables

  • Mana

    The unit-level resource that gates ability casts. Mana-gen items, on-cast refunds, and starting-mana augments all key off this mechanic.

  • Heal

    Restores Health to a unit, capped at maximum HP.

  • On Cast

    Effect fires the moment a unit casts its ability. Spellslinger / Jeweled-Gauntlet payoffs key off this.

Innervating Locket scales with

  • Max Health

    Grants the unit additional maximum HP — flat (`+150 Health`) or percentage (`+6% max Health`). Item HP, augment HP boosts, and ability bodies that read "Gain X max Health" all land here, including Cho'Gath's per-cast "permanently gain max Health". The cross-round permanent-stat angle has its own curated landing at `/permanent`.
