Rank 4 by 0.4 seconds
Rank 5 by 0.5 seconds

Commentary: This talent saves a lot of time when casting your Healing Wave. This reduction of time makes it so there is less time for the spell to be interrupted, and also less time for the heal to happen.

The exception to this is on PvP servers you might be attacked without notice until it is too late. This is a useful talent for when you are close to finishing off your opponent and they get that lucky break to kill you. You die, you can then Reincarnate right next to them with 40% of your life and mana if you have this talent maxed out. Many times you can catch unknowing players off guard by reincarnating next to them when they thought you were dead.

Description: Reduces the threat generated by your healing spells
Ranks: Rank 1 by 5%
