You gain a health threshold equal to 70% maximum health which cannot be modified nor exceeded by any means. In return, you deal bonus true damage equal to 15% of all of the damage you deal pre-mitigation.

Avoid Ominous Pact + Glass Cannon

Glass Cannon sets your health threshold to 70% maximum health, which directly conflicts with Ominous Pact's design that rewards you for reaching 70% missing health. You cannot access the full AP, movement speed, and omnivamp scaling that Ominous Pact provides, making this pairing fundamentally incompatible and wasteful.

You can no longer be healed by allies and your health regeneration is set to 0 . Gain 25% omnivamp .

View augment details

Avoid Ominous Pact + Vampirism

Vampirism sets your health regeneration to 0 and prevents ally healing, while Ominous Pact costs 5% current health per ability cast. The 25% omnivamp from Vampirism is redundant since Ominous Pact already grants up to 20% omnivamp based on missing health, and the anti-healing mechanic undermines your ability to sustain through the health costs.

Avoid Ominous Pact + Celestial Body

Celestial Body grants 1500 bonus health but reduces your damage output by 10%. The larger health pool means Ominous Pact's 5% current health cost drains more absolute health per cast, while the damage reduction diminishes the value of the AP you gain from missing health scaling.

Avoid Ominous Pact + Perseverance

Perseverance grants massive base health regeneration, but Ominous Pact's health costs scale with current health rather than being mitigated by regeneration. The regeneration effect provides minimal value during active combat when you're rapidly spending health on abilities, and the two mechanics have poor synergy together.
