Jolting chain and the force feedback +recharge proc- with no local recharge, how often would it proc?

[EnjoyTheJourney]

I'm building an electric / storm / psi troller. So, having a lot of recharge is very appealing to keep multiple nados / lightning storms out on a regular basis. I'm hoping that jolting chain can help with achieving that goal. 

Thus, I'm wondering roughly how often a force feedback +recharge proc in jolting chain would proc when there is no local recharge slotted into jolting chain. This would be a team play troller, so spawns will be large and most of the time jolting chain will hit anywhere from several to up to 16 targets. I'll have a force feedback +recharge IO in tornado and in lightning storm as well, in case that matters for figuring that out.

Short answer: It will proc about every other cast on a large pack and very rarely on single targets.

 

Long answer: You're looking at a minimum chance to proc regardless of slotted recharge because the chain PPM formula is pretty unforgiving. However, since you're still hitting a lot of targets with it due to its target cap and how often its up, it's good to slot it. Just don't rely on it for single target fights.

It sounds very much worthwhile to slot then. Thank you for the information.
