Passive: 15 / 23 / 31 / 39 / 47% of damage Tahm Kench takes is stored by his Thick Skin, increased to 42 / 44 / 46 / 48 / 50% if there are at least 2 nearby enemy champions. If Kench has not taken damage within 4 seconds, Thick Skin will rapidly be consumed to heal Tahm for 60-100% of its value (depending on level).
