What is the meaning of "Proc" and "Channelling"?

[A.C Hater]

Hey guys,

Enjoying this game in my short time playing it, but not understanding some of the lingo. In particular, Proc and Channelling?

So I've running a rogue Marksman bow build and currently using the Flurry skill. I see there is a channelling skill within the tree which uses Mana. My question is, why would I choose this and deliberately use mana as right now I can spam it without it affecting my mana at all?

Also, I want to use Multishot later and have read a lot of guides which suggest "proc"ing Flurry with Multishot, what does this mean?

Can somebody explain it in the most simple terms lol thanks in advance :D

A "proc" refers to the chance of an ability, attack, spell, etc to cause something to happen. For example there's passives and such where if you kill something with an ability that there's a "proc" that is a chance that an explosion will occur.

"Channeling" refers to constantly using that ability with mana drain and something to constantly happen. An example of that is the Lich class has an ability called Life Drain where you can use it on an enemy and you'll constantly use Mana and drain the HP of that enemy.

As for why you'd use the channeling skill that's up to how the skill works, it's benefits, etc and how your build works.

Proc = chance to active something else when you use a power. (Direct damage effect or damage over time effect, buffs, etc, no matter what power it is, it's a chance to active a second effect to your power).

Channelling = do his effect as long as you continue to use the power. If you stop to use it, the effect stop immediately too (or shortly if the power has a duration).

Edit: A channeling power can have a proc, it's not exclusive.

In your guide's example, when you're using multishot, you will have a chance to active the flurry effect on top of the multishot damage you are doing normally.

[Kotli]

Proc = a skill/power that triggered by something else.
Channelling = skill is cast/used non stop in return for a constant mana drain.
BTW you got it backwards its Flurry that procs multishot when you take the Fusillade node (100% chance on the 4th attack).
