The thing about Crit is
What happens if Crit Spec with Hallucination is combined with Spec Swiftness is combined with Salvation to aid Shadowhunter? In general, those who invest in Crit Spec choose Salvation to increase damage and those that invest into Spec Swiftness choose Hallucination to get the Crits. Let's take a look at an engraving of 5x3 for the present absolute ending game scenario.
Let's say I choose a 4x3 crit with Grudge, Demonic Impulse, Raid captain, and spirit absorption to help with the speed of movement. If I purchase the hallucination sets, I receive an additional 20% in damage as well as 25% more Crit. The maximum you can currently put into Crit Spec is like 550 (about 20 percent) and 1600, respectively. This will give you 75% crit percentage in the demon mode. But at the end of the game, you're not getting damage. What if you put keen blunt to create 5x3? It will give you an extra 50% damage for crit, and with 75% crit it means it nearly always will be crit.
Let's suppose that one with spec-slowness is going to Salvation. You can increase your speed by around 10% with necklace. Salvation grants an average of 47% damage. it is recommended to go for Demonic Grudge, impulse and raid captain as well as adrenaline for increased crit. The reality is that holding 6x adrenaline for all of the time is practically impossible. What happens when you throw something like a precise dagger in the mix to make 5x3.
Do you know of these builds, or has checked? We'd appreciate it if you could let us know.
The issue with Crit is that both damage and the Crit rate are both additive but Crit Rate is more detrimental because it has a limit of 100%, and if you surpass that limit, it's a useless stat.
The reason for people to go Salvation for Spec/Crit build is they can have another damage engraving, instead of Spirit Absorption for speed of attack. Most commonly, it's Cursed Doll, Hit Master or Adrenaline. With the combination of Salvation and Yearning you're at maximum attack speed, and when you are using Spirit Absorption you'll go over the limit and should use the engraving points into a different damage engraving.
In the case of the Spec/Swift version They run Hallucination to compensate for the loss in crit and will limit the attack speed and move speed along with Yearning naturally. It's not worth it to go Salvation to the point that you're not getting the advantage of the extra attacking speed Salvation gives. A precise dagger isn't a good engraving since you lose damage the higher Crit Rate you've got. If you're suffering from Adrenaline + hallucination, then you're already with 75% Crit rate, without class synergies of the cheapest lost ark gold. This is already high enough. In addition, adding PD isn't even an improvement in your damage. Better to use an additional 16% damage boost engraving such as the hit master. PD + KBW should not be used together. It's a complete contradiction and causes KBW more difficult.
