Rune of Jera

A rare head armor from the Rune set that doubles both passive and active trinket effects via TrinketPassiveMultiplierBonus and TrinketActiveEffectsMultiplierBonus. Jera is exceptional for trinket-heavy builds, effectively doubling the value of every trinket you carry without the stat penalties found on the Cap and Bells. Part of the Rune set with Rune of Perthro and Rune of Hagalaz — combining all three layers each piece into a potent offensive and utility powerhouse.

Unlike Copycat Hat, which only doubles passive trinket effects, Rune of Jera doubles both passive and active trinket effects simultaneously. Active trinkets like Pawn, Rook, or Queen have their ability effects doubled when activated — a doubled Self-Destruct Button, doubled Metronome result, or doubled Chess piece effect dramatically changes what those items can do. This makes Jera uniquely strong in mixed passive+active trinket builds.

Rune of Jera is one of the strongest head armors in the game for trinket-reliant builds. It outperforms Copycat Hat when you're running active trinkets alongside passives, and it provides this value without any negative stats. In the full Rune set, Jera handles trinket amplification, Hagalaz handles weapon amplification, and Perthro provides survivability — a clean three-way coverage of offense, utility, and defense.
