Optimal damage scaling? [Callidor's Tempest DPS]

Hi!

I’ve been wondering about the way I should value different stats for min-maxing purposes. Now from what I’ve read it basically goes something like this, right (assuming sufficient OA to always hit at least)?

(Spell damage + flat damage * wpndmg component)casts per second%damage increases*average crit multi modded by crit %.

Now obviously there’s still resistance reduction which is really important but since it’s related to the monster I’d rather keep it out of this. I know it’s the same for OA and crit chance but I feel that resistance reduction is something you want to get pretty much as much as you can anyhow (when using elemental damage).

Doing the first part of the calculation and using lvl 25 CT with flat damage from skills + weapon after the 0.53 multi I get a base damage of 353-574 -> ~463 average. This is basically where the problems start; so ok cast speed is maxed at 200% but does that actually make the cast twice as fast compared to 100% or does it affect it more than that? What even is the base cast speed of CT? Using a fairly low incr damage % value of 1200 may result in this exercise becoming moot but there it is. Now then the extra damage granted by crits against endgame bosses is also bit of a mystery to me but let’s say I have 2800 OA and 85% inc crit damage for 110% PTH, 20% of the hits being crits at the average of 1.275 multi.

Filling the formula in with expected values results in:
463213*1.425 = 17154.15 (can’t call it dps since that cast speed is most likely off)

Basically it seems to come down to how much OA it takes to increase that crit multi/s. Roughly increasing the multiplier by 0.1 is the same as increasing the damage % by 91 with these values. How much OA that takes and how much the base crit chance grows with it is probably the critical question in this case. The flat damage part seems prohibitively difficult to increase through gearing any more than where it currently sits.

I hope this makes some sense instead of seeming like madman’s ramblings and you guys have some ideas how to get the figures closer to reality. Thanks for the help!

Ok so after doing some research I found this topic: http://www.grimdawn.com/forums/showthread.php?t=56478

Looks like I messed up the crit multi calculation by overestimating the effect of crit damage.
I also tried to just roughly count the amount of casts for CT using a stopwatch @ 134 inc cast speed. After giving it a few tries I got something like 10 casts in 4,5 seconds. Also looking at youtube videos of people with 200% cast speed casting CT at 0.25 speed gives about 4-5 casts in a second.

So, looking at it again;
463413*1.2 = 28891.2 dps

Dragging the crit multi up is a fairly frustrating project even accounting for -defensive ability skills, so in this case it seems like it’s best to just to try to get more inc damage % and flat damage and let the OA come somewhat naturally without specifically focusing on it too much.
