On what moment is its damage calculated? Is it calculated on its proc (with all current bufs and players in range modifyers) or on cast?
E.g. I have proxy det on my off bar. And I have maglite on my main bar. If I cast proxy det then switch to main bar gap close and attack enemies with sap essence. Will be detonation calculated with major sorcery (from sap essence) and major prophecy (from maglite) buffs that were not active on it's activation?
