It "fades" 5 times.
Or...The only way the tooltip could be accurate in the current implementation is if you consider the original casting of the spell the first jump
Thisuglyguy casts Prayer of Mending at Thisuglyguy.
Thisuglyguy's Prayer of Mending fades from Thisuglyguy.
Thisuglyguy's Prayer of Mending heals Thisuglyguy for 1478(2021 Overhealed)
Whichuglyguy gains Thisuglyguy's Prayer of MendingIf harky's logic is correct, which it is, it's already happening. Someone has Mending fade from them, it heals, then it lands on someone else. The "jump" doesn't refer to a "land".If harky's logic was correct, then you would absolutely see that in the combat log, followed by it fading away (without any healing)... that just doesn't happen, no matter how much we wish on pixie sticks it does.
If someone "jumps" off a bridge, you don't disqualify that if they have a bungee cord that stops them from hitting the bottom. The act of "Jump" in harky's logic is dictated by it leaving a target, which has the context of adding a heal. It does this 5 times.
