Eidotrope at OutDPS: As an on-use trinket with no passive agility, the Kiroptic Sigil may not seem all that appealing. It also does not compare favorably on spreadsheets with other trinkets this tier (as Frostheim discusses here). However, it ends up being better than we might first expect.
The trinket’s on-use cooldown of 2,290 agility for 15 seconds every 1.5 minutes makes it remarkably useful this tier.
