Gold Efficiency	97.17% (adds +94 Ability Power from the start)
Unique Passive(s)	Warlock: Ability Power +35%.

Hecate’s Diadem is the premiere offensive magic item in Arena of Valor. Once you hit 500 ability power, Hecate’s Diadem offers more additional ability power than Holy of Holies. In addition, its magic pierce rips through squishy targets (and tanks who have forgone magic defense) on the other side (read more about calculating pierce damage or how pierce percentages are calculated).

Recommended Heroes and/or Situation:

The damage potential that Hecate’s Diadem offers makes it an invaluable pick to nearly all offensive mages. Supports can benefit from it as well, the ability power making their heals and shields all the more effective.
