The ability that stuns will count toward the next stun.
Incinerate and Summon Tibber will stun all enemies hit.
Molten Shield's reflected damage and Tibber's damaging aura will not apply the stun.
The stun applies to the first ability that lands when the stun is available. If you cast Disintegrate followed by Incinerate while the stun is available and Disintegrate is in the air, the stun will apply to Incinerate. If the target dies or the ability is blocked, it spell still counts as having landed and the stun will be consumed.
