Tentacle Slam enables

  • Heal On the Menu

    Restores Health to a unit, capped at maximum HP.

  • Summon On the Menu

    Adds a unit to the field — temporary or permanent. Covers ability summons (turrets, pets, Mega Meeps), trait-spawned minions and relics (Shepherd's Bia/Bayin, Bulwark relic, Primordian Swarmlings), resurrect/revive of fallen allies, and bench-to-field arrivals (Thresh's Lantern pulling a benched unit). Summon-buff augments scale these. Bench-slot expansion is the separate `bench` mechanic; an exact copy of an existing unit is the separate `clone` mechanic.
