So you want an automated way to help with mana management?
I am sorry to disappoint you, but EHG is actively working against that.
Both fo the ways I named previously worked for non direct casting and that got chagned, because it is not in the mind of the devs to have such things.
I personally think that such thigns are ok, if they are on uniques and have a noticeable downsides, that gives that way of mana management a huge flavour.
But a solution to basically trivialize mana and never think about it again is something that I personally don’t like and the devs seems to be on the same page with that.
I can see that after what they did to Volatile Reversal…
For having either Javelin or Hammer Throw as a main damage skill the mana cost is too high without always getting the cost reduction nodes + the ring affixes for mana reduction.
There’s not much choice and there’s not enough benefit since they’re required and neither skill are powerful enough to justify the high mana cost.
Since most throwers use the Smite on throw hit idols, which already takes up all the slots, giving Smite that extra benefit would justify the cost and investment.
But it can already give you a good amount of extra attack/cast speed. IMO, I dont think this is necessary other than to trivialise mana even more for a Sentinel.
If you’re using Smite (proc’d via idol) for dps then you’ll either be using a staff or wand which means it’s free or you’re using it as a utility for the attack speed, heals and cleanse in which case you’re probably not needing the extra few mana every few seconds. And if you’re spamming a throwing skill you should be using the ring cost reduction prefix to bring the cost down as much as possible.
