Quick answer

Choose one compatible status per weapon, then prioritize permanence

A melee weapon and sidearm each have an Infusion slot. Early levels may require Resolve and provide a limited number of infused hits; current gameplay commentary shows key Infusions becoming permanent at the final retail upgrade. Gameplay guide

How Infusions work

  1. 01
    Equip the stone in the Infusion slot of a compatible melee weapon or sidearm.
  2. 02
    Activate it when required, spending Resolve and receiving a limited application.
  3. 03
    Earn kill XP while it remains equipped.
  4. 04
    Temper it; the final retail tier may make the infusion permanent.

Why Infusions are strong Level 3 candidates

Removing repeated activation saves Resolve and makes status application consistent. Players describe lower-tier Infusions as awkward because activation can take longer than the short effect lasts. Community discussion

How to choose an Infusion

  • Confirm compatibility.Many Infusions do not fit every weapon.
  • Match hit pattern.Fast weapons favor repeated application; slower weapons need a payoff worth each hit.
  • Budget Resolve.Do not starve Shell, sidearm, or Ability actions just to maintain a weak temporary infusion.
  • Test before Level 3.The permanent upgrade is expensive and no refund is documented.
