Since you can swap to the best covenant as needed. With the changes to patch 9.1.5, the way you evaluate covenants has gotten a lot different. The cooldown is reduced by 30 seconds if it does not last its full duration. If the target lives, they take another burst of nature damage, and you gain 1 use of any stealth ability for 5 seconds. Night Fae: Sepsis causes the target to take nature damage over 10 seconds. This effect lasts until death, and It has a 30-second cooldown and three charges. Necrolord: Serrated Bone Spike deals physical damage and causes the target to bleed every 3 seconds.
Each combo point spent also grants 1% haste that lasts for 12 seconds afterward. Venthyr - Flagellation deals shadow damage and causes each of your combo points spent to deal reduced shadow damage for 12 seconds. Finishers used on the matching animacharged combo point deal damage as if it were 7 combo points. Kyrian - Echoing Reprimand deals arcane damage, generates 2 combo points, and animacharges the 2nd, 3rd or 4th combo point.
