Does lifelink from multiple creatures stack so you gain life from each one separately?

Lifelink is a static ability that causes damage dealt by the creature to also cause its controller to gain that much life. Each creature with lifelink tracks its own damage independently, so if multiple creatures with lifelink deal damage, you gain life from each one separately. This is explicitly supported by CR 702.15b, which ties the life gain directly to the damage event of that specific permanent.

Importantly, lifelink does not use the stack — the life gain happens as a consequence of the damage being dealt (CR 702.15a). Each damage event from a different source resolves its lifelink trigger as part of that damage step, not as a separate triggered ability. This means multiple creatures each contribute their own life gain without any cancellation or cap.

There is no diminishing return or stacking restriction. If you control three creatures with lifelink dealing 3, 2, and 1 damage respectively, you gain 3 + 2 + 1 = 6 life total. Multiple instances of lifelink on the same creature are redundant (CR 702.15b), but across different creatures each instance functions fully.

Example: You attack with a 3/3 lifelink creature and a 2/2 lifelink creature, both unblocked. The 3/3 deals 3 damage to the opponent, so you gain 3 life. The 2/2 deals 2 damage, so you gain 2 more life. You gain 5 life total that combat step.
