So even if it is not used for healing. Being able to have a full globe every 5-7 seconds is nothing to glance over either. (^-^)b
How are you getting a full globe every 5-7s when it has a cooldown of 15s? At 3APS you would gain approximately 65 spirit from that rune every 15s for a single target, and a full globe more than likely with more than one enemy.
Glad you asked Void (^-^)
"Infused with Light
Gain 6 additional Spirit from Spirit generating attacks for 5 seconds after using Breath of Heaven."
I base my numbers off having a APS of 2.5 which seems reasonable with duel wielding.
Pop BoH (12.75 CD timer starts with Beacon of Y'tar passive)
The next 5 seconds is you attacking with your generator as much as possible. (CD remaining on next BoH is 7.75 seconds)
With 2.5 APS this means over that 5 seconds your going to land 12.5 attacks. Lets round down to 12 for even numbers.
12 attacks @ 12 spirit per attack = 144 spirit generated during those 5 seconds. A full globe
So now we have a full globe and 7.75 seconds on our CD. Well we need to spend this spirit don't we? So how much time will it take to blow 144 spirit? Could be 2 seconds with spamming skills like Mantras(50) CS(50) WoL(75). I was guessing that 2 seconds was a reasonable number of time that would pass while your blowing that full globe.
This leaves us 5.75 seconds on the BoH CD before we can rinse and repeat.
So during the next 5.75 seconds, you have 0 spirit cause you just dumped it and so your going to spend this time filling up your globe again.
5.75seconds x 2.5 APS = 14 attacks roughly @ 6 spirit per attack. 14 x 6= 84 spirit generated.
Now you have 84 spirit, your BoH CD is up and you can blow 84 spirit, pop BoH and start all over.
I say 5-7 seconds because if you dont use Beacon of Y'tar passive. Its more around that 7 second time.
Yes i know its literally 12.75sec on the CD or 15sec but you will be busy either spending or generating.
Because if you dont spend that time spending and or generating then whats the point of having the skill?
You can see though how you will be blowing through 100's of spirit very quickly in a short amount of time over and over. Thus making BoH our fastest spirit gen skill we have.
Add to this any gear with spirit regen or other skills that add to spirit regen and you will have more spirit then you know what to do with (^-^)b
