So I was going through the legendary items that wowhead datamined and came across this:
ww.beta.wowhead.com/item=133973/hidden-masters-forbidden-handwraps#see-also
"If Touch of Death does not kill your target, they will suffer its effect every 30 seconds until they die."
The new ToD which is useable at any HP reads.. "Use ancient Pandaren knowledge of anatomy to inflict mortal damage on an enemy. After 8 sec, the target will take damage equal to the monk's maximum health (damage reduced against players)."
Does this mean... Let's say on Pull I use ToD on a boss.. let's call it ToD1 - it don't kill boss, legendary dot that ticks every 30 secs(Legen1) for ToD1 activates.. 2 min's into the fight, Legen1 dot is still ticking and I do ToD2 this time since it has come off CD, so Legen2 - 2nd dot for 2nd ToD activates... 6 mins into fight 3 dots of ToD? providing Boss doesn't die.
