History of Resonate Stem

Resonate Stems are an Uncommon consumable and currency from Season of the Seraph (Season 19). They have a maximum quantity of 32 and drop from completed activities only while the Resonance Amp is in your inventory. Your current stock is shown on the Amp's tooltip.

Uses

• Resonance Amp: Activating the Amp consumes 4 Stems to generate an Override Frequency. The frequency points to a Warmind Node on the Moon or Europa, or in the Operation: Seraph's Shield exotic mission. The Amp becomes inactive once all Warmind Nodes are found.
• IKELOS focusing: Focusing IKELOS Weapons at the Exo Frame in the H.E.L.M. costs 4 Stems each, once the IKELOS Weapon Focusing upgrade is unlocked. Each focus also costs an Umbral Engram and Legendary Shards.
