[3.14] Champion Relic of the Pact Petrified Blood | Snap Cast Channel | Tank Version |

Relic of the Pact gives a level 1 Spell Skill called Blood Sacrament



It is a channeling skill that will reserve 3% of your life per channel cast.
So in this case, if we stack Reservation of Skills to a point where we reserve 49.89% of our life per cast, we would only need to channel once for maximum benefit while using Petrified Blood.

To reach 49.89% life reserved per cast, we use:
Gems:
Lifetap - 200% Mana Multiplier
Arrogance - lv 1 - 220% Mana Multiplier
Increased Area of Effect/Concentrated Effect - 140% Mana Multiplier

Tree Node:
Supreme Ego
50% More Reservation of Skills

Equipment:
Essence Worm x2

40% Increased Reservation of Skills each.

Math:
3%
200% (Lifetap) *
220% (Arrogance) *
140% (Conc Effect) *
150% (Supreme Ego) *
(1 + (40% + 40%)) (2x Essence Worm)
= 49.896%

Which rounds to 49.86% in PoE

The original goal was to reserve an lv 1 Vitality gem with Arrogance support so we instantly finishes the channel since there are less than 49.86% life to reserve after one cast.

However, I realized that it is essentially casting twice to deal damage, once to reserve, once to release.
Plus I want an lv 21 Vitality for more defence.

So if we cast Blood Sacrament and instantly release it, we would essentially double our dps compared to channeling the skill. But for this to work, we need to cast our skill on the server tick rate.

Cast time:
So the breakpoint of the cast speed would be the multiples of the server tick rate: 0.033s.

In the video above, my cast speed is a bit lower than 0.165s, which is 5 ticks. Also seemingly the best cast time in my experience for the skill.

So you want your skill's cast speed to be at
<0.132 cast/s | 7.58 Cast Rate
<0.165 cast/s | 6.06 Cast Rate
<0.198 cast/s | 5.05 Cast Rate

Realistically, <0.132 cast/s is going to be very hard for us to achieve.
So we target <0.165 cast/s
This is the result of jumping to <0.165 cast/s Cast Rate
