DRK - Is it worth using Dark Arts Bloodspiller without Grit?

[Tankstuff]

but this skill have 80% damage increase if you are in grit, so you actually gain damage here

its literally the exact same damage whether youre in or out of grit, you people are bad at math lol

but this skill have 80% damage increase if you are in grit, so you actually gain damage here

Bloodspiller Potency : 380
In Grit potency : 475, but since Grit reduces damage done by 20%, the effective potency is 475 * 0.8 = 380
And no, it does not ignore damage penalty from Grit, if it does it'd have specified so like WAR's Inner Beast

DA Bloodspiller : 520
Grit + DA Bloodspiller : 650 * 0.8 = 520, same deal

Not sure where did you get this 80% from though.

For now, having increased potency under Grit or ignoring Grit's penalty is the same.
However, if one day we have a skill like Unchained, then we could pair this skill and BloodSpiller to gain even more damage.

Darkside only (1.2x modifier)
The net benefit for using DA on SpS is:
1.2(390) - 1.2(250) = 168 potency

The net benefit for using DA on SE is:
1.2(420) - 1.2(280) = 168 potency

The net benefit for using DA on BS is:
1.2(520) - 1.2(380) = 168 potency

The net benefit for using DA on C+S is:
1.2(475-100)/2 DA = 225 potency

NB: this costs 2 DA to use, as the base ability gives you 1 DA when used without DA.


Grit + Darkside (1x modifier)
The net benefit for using DA on SpS is:
390 - 250 = 140 potency

The net benefit for using DA on SE is:
420 - 280 = 140 potency

The net benefit from using DA on BS is:
650-475 = 175 potency.

The net benefit for using DA on C+S is:
475-100/2 = 187.5 potency

With Grit off, it doesn't matter whether you use DA on a combo action or BS. Use it on whatever GCD you like, in order to ensure that you don't cap on MP. With Grit on, you should always DABS, as it's worth 35 more potency than a DA combo action. DA C+S still takes precedence in both cases.

Since grit lowers damage by 20 percent for off tanking it's better to do it without activating grit

This is incorrect.

There is bonus potency for using DA+BS while in Grit. And the bonus potency is exactly what you need to make up for the 20% damage reduction in Grit.

So to answer the OP: They are exactly the same. The net potency between DA+BS out of grit or in grit is exactly the same.

Basically the TLDR here is; Bloodspiller has the same effective Potency regardless of if you're in grit or not, so the priority is basically always the same regardless of if you're in or out of grit. Please feel free to correct me.

This is correct but with one caveat, being that Bloodspiller doesn't necessarily have priority over SS/SE out of Grit. In Grit, it does. This is why artificially inflating your BS usage with TBN is a gain in Grit but a (very, very slight) loss out of Grit.
