Stay in melee, fill Resolve, dump it immediately, refill with lights. That loop is the whole game. Resolve does not refill on its own - if you back off, hoard the bar, or mash without committing, you starve yourself of the tools that actually win fights.

1. Hit in melee
Committed 3-4 hit strings fill the gold bar
2. Spend it now
Shell ability / weapon special / sidearm shot - many have i-frames
3. Refill, repeat
Two or three light attacks refill the bar. Never sit on a full meter

1The Earn-Spend Loop, Step by Step

2Pick the Loop That Fits Your Fight

SituationWhat works
New / dying to animation lockVatra's Seal + roll into attacks + short committed light strings
Want burst / glass cannonTiel + Axe & Dagger + Trebuchaxe: Shadow Dash → Shadow Strike (Poison/Fragile) → lights to refill → charged sidearm crit. One mistake deletes you.
Stay in the enemy's faceProxima + Axatana: double-hit lights refill fast; spam Biosampler / Seizure; tank with Grafted Armor. Upgrade Biosampler damage and the mitigation node.
Sidearm-heavy playstyleDevout Stone so kills pay the meter back. Do not main a weak crossbow or you will always be empty.
Pack of enemiesSpend Resolve immediately on a CC / i-frame ability, refill on whoever is left standing.
