Avoid Empyrean Promise + Vampirism
Avoid this pairing because Vampirism completely nullifies Empyrean Promise's ally-shielding utility. Vampirism sets your health regeneration to 0 and prevents you from being healed by allies, meaning the shield you grant to your teammate upon arrival cannot be supplemented by any ally healing, and you cannot benefit from team support synergies that Empyrean Promise enables.
