After some testing, it does appear that Arcane Dynamo affects the entire duration of a single channel. I haven't seen anything on the forums indicating that this changed occurred, thus I just assumed the former to be true. Shot myself in the foot this time
So this does offer an alternate path towards "late-game" gearing. Instead of aiming for enough AP generation to drop your sig spell, you could use Arcane Dynamo and keep it, freeing up affixes such APoC and RCR on your gear since you can use a sig spell to regenerate AP when you run out. And with AD you'll want to pop off 5 sigs in between channels for that 60% buff anyway! Thanks for bringing this to my attention, will update the signature spell section accordingly.
I really appreciate your feedback wuffiliate, thank you!
Swordsman83, sorry I'm a noob >.> but I'm very glad you asked!
It was brought to my attention through this thread, which completely switched me to arcane from cold haha. It's pretty insane. I play a very similar tanky arcane build, and i enjoy it immensely.
Actually, it does work for the full duration of the channeled spell. I just tested it again to make sure, it 100% works until you stop channeling. It's easily the highest damage passive you can choose for this type of build.
Damage wise lightning isn't the real maximum damage spec, exploding palm puts cyclone to shame and does FAR more damage. More work into this mechanic can lead to far more damage than typical builds with a spirit generator. It's possible to get up to about 3 seconds of downtime on Epiphany.
While this may be a functional build without spirit generator, I am pretty sure that traditional lightning builds will out damage it since you don't have to make sacrifices and sweeping wind does A LOT of damage. I also doubt this build is capable of spamming LTK on every mob without running out of spirit, even with all these spirit generating cooldowns and passives.
Did you even watch the video he provided? It's clear he CAN spam LTK constantly, with epiphany only having about 8-9 seconds of downtime means it's up 90% of the time leaving him spirit capped constantly and was easily clearing T3 solo.
This build definitely looks primising with the right gear set, so glad i have a ton of CDR gear from my normal speed run TR build gear lol.
