Question about channeling mana cost

[Kamiyama]

I'm looking at making a build that uses Cyclone. It is a melee attack channeling skill with a cast time of 1 second.

If my character has lots of improved attack speed - uses frenzy charges, onslaught, faster attack support, attack speed nodes, and has an "attack rate" (as shown in path of building - but not a thing on the wiki) of 10 what does that mean?

Does he attack 10 times a second with cyclone? Does it still cost 7 mana a second to channel, or does it cost 70 mana a second to channel?

When channeling a skill, you spend the mana cost each attack or cast. So it's dependant on your attack/cast speed.

And yes, it's going to be 70 mana/s if you do 10 attacks per second.

About cast time, it's not what you think it is. It's something to prevent skills from overlapping. Cyclone has a cast time of 1s, meaning you can't cast another skill (exception of cast time breaking skills, like travel skills) in that second while cyclone is in use, you have to wait to cast the other.

Thank you for clarifying that.

Right now it seems my build has a bit of a mana problem. =/

There are various ways to manage mana consumption. There's how much you regenerate, which can be affected by gear, and by various passive nodes. There's mods that reduce mana used (Elreon mods). There's also mana-on-hit mods.

You can also use a Mana Leech Support gem. That might not be ideal for what you're building, but it still might make it possible prior to the point where you've got your passive tree in it's final state and gotten your end game gear.

There's an Aura gem (Clarity) that regens mana too. Or, run Blasphemy Support and Poacher's Mark (or Assassin's Mark, or Warlord's Mark).

Play around, balance it so that you're not using mana faster than you're regenerating it.
