While Tahm Kench has an ally in his belly, he gains 30 / 35 / 40 / 45 / 50% bonus movement speed while moving toward an enemy champion. If he has an enemy champion in his belly, Tahm Kench removes their shared vision and reduces their sight radius to only their immediate surroundings, but also slows himself by 95%.
After a brief delay, Tahm Kench gains the ability to recast Devour, spitting out the swallowed target. If the target is an enemy champion, minion or monster, they will take 20 / 23 / 26 / 29 / 32 % (+ 2% per 100 AP) of their maximum health as magic damage (this damage is capped against monsters). In addition to this, minions and monsters will be spat forward, stopping if they hit an enemy or terrain and dealing 100 / 150 / 200 / 250 / 300 (+60% of ability power) magic damage to all enemies in an area. Upon exiting enemy champions will get stunned for 0.25 seconds.
