  • Max Health On the Menu

    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`.
