How does Invigorate work (velious chest clicky)

[maxlaurent]

Hey, I just realize that some Velious chest armor have clicky "Invigorate" on it :

https://wiki.project1999.com/Grand_M...7s_Chest_Wraps
For monk for example, wiki says the casting time is 15.0 sec. But is there a recast time ?
I mean, if u get this Velious chest armor for my 46 monk, I could heal 115hp every 15 sec ? If so, fungi tunic becomes totally useless between fights right ?

Thanks for help !
