5 seconds after combat starts, [Life Link] is activated with the 3 ground allied heroes with the greatest damage taken (re-evaluated every 5 seconds). When this unit's HP first drops below 50%, it transforms into [Earth Spirit] and protects the ground ally with the highest physical attack. The chosen ally gains 40(100)% of this unit’s HP cap, becomes immune to control effects for 8(20) seconds, and, if dealt lethal damage during this period, is invincible for 3 seconds and the guard ends early. [Life Link]: Boosts damage reduction by 20(50)%, restores HP each second equal to 40(100)% of Houtu’s magic attack, and causes 50% of incoming damage to be taken by Houtu. Cannot be dispelled. [Earth Spirit]: Cannot be targeted or damaged by either faction while active.
