Heart of the Swarm enables

  • Summon

    Adds a unit to the field — temporary or permanent. Covers ability summons (pets and minions like Fizz's Mega Meeps), trait-spawned minions and relics (Shepherd's Bia and Bayin, Bulwark's placeable relic, Primordian Swarmlings), resurrect/revive of fallen allies, and bench-to-field arrivals (the Thresh's Lantern artifact flings a benched unit onto the board). Summon-buff augments scale these. Bench refers to expanding bench slots, not the act of summoning; clone refers to making an exact copy of an existing unit, not summoning a new entity.
