Tahm Kench Heal Bug

When Tahm Kench uses Devour on an ally, the summoner spell Heal can be used without the movement speed and without it going on cooldown. Both, the ally and Tahm Kench get the Heal of the summoner spell when Tahm Kench spits his ally out. This works only, if the allied Champion doesn't have the summoner spell Heal, but Tahm Kench does. All you need to do to get this bug, is to spam left click next to Tahm Kench when you are devoured by him. The heal applies to Tahm Kench and his ally and you can see the particles of the Heal as well. The bug worked with a Nocturne with Flash and Ignite and a Tahm Kench with Flash and Heal.
