Zeta

Zeta Ability Materials were introduced to Star Wars: Galaxy of Heroes in 2017 and became the first true "premium" upgrade currency in the game. A Zeta lets you push a qualifying ability past its standard max tier, unlocking new mechanics like additional turn meter swings, expanded buff durations, or entirely new effects on the kit.

You earn Zetas mainly through the weekly Mod Battles store (limited stock that refreshes every Monday), the Mod Challenges, Conquest reward crates, and occasional events. They cap at a slow trickle — most players accumulate 4 to 8 per week, which makes prioritization essential.

Priority strategy: feed Zetas to your top Galactic Legend or meta squad first. Iconic examples are Darth Malak's "Drain Life" (the entire kit hinges on it), Jedi Knight Revan's "Order of the Old Republic" leader Zeta (defines the JKR squad), and General Grievous's "Daunting Presence" (Separatist meta). Wasting a Zeta on a low-priority unique or leader can stall your roster for weeks.

Zetas are still relevant in 2026 even with Omicrons taking the spotlight — every Galactic Legend requires multiple Zetas as part of their unlock chain, and most endgame squads rely on at least one Zeta-defined ability to function at full power.
