How does Endurance recovery work in Valiant?

Endurance recovers once per 15-minute tick, at the very start, before any fighting. You regain 5% of your maximum Endurance plus your Endurance Regen stat. It then drains across that tick's encounters and tops up again at the start of the next tick.

How much Endurance does each fight cost?

Endurance is spent per encounter based on the enemy's rarity: 3 for a common, 8 for a rare, 20 for a world boss. Individual talents and abilities do not have their own Endurance cost - the whole encounter drains a flat amount.

Why does Endurance matter?

As Endurance empties, a scaling factor reduces your offense and defense down to a 50% floor. A fatigued character hits softer and takes more. Keeping Endurance high keeps you at full strength, which is why Endurance and Endurance Regen are quietly among the most valuable sustain stats.

Endurance

Endurance is your stamina across a tick. It recovers once at the start of every 15-minute tick, drains as you fight, and quietly scales your entire character up or down based on how full it is. It is one of the most misunderstood - and most valuable - stats in the game.

Your Endurance pool

You start with a base of 100, plus any Endurance from gear, inscriptions, and the Fortitude attribute (+1 per point). A support-stance companion adds more.

Recovery: once per tick, at the start

This is the part players miss. Endurance does not trickle back during a fight. It refills once, at the very start of each 15-minute tick, by:

5% of max Endurance + Endurance Regen

Then it drains across that tick's encounters. So within a single tick your Endurance only goes down; it tops back up at the start of the next tick. (Fleeing a fight fully restores it.)

Drain: per encounter, by enemy rarity

Enemy rarity	Endurance drained
Common	3
Rare	8
World boss	20

Note

Endurance is spent by the encounter, not by individual talents — there is no per-ability Endurance cost today. The only talent that touches it (the Natural Defender line) reduces the drain rather than adding to it.

The hidden scaling curve

Here is why Endurance matters so much. Before each fight, your current Endurance fraction is turned into a multiplier on your offense and defense:

multiplier = 0.5 + 0.5 x (Endurance / max)^0.7

At full Endurance you fight at 100%. As it empties, your damage and mitigation modifiers slide toward a 50% floor:

Endurance	You perform at
100%	100%
75%	~91%
50%	~81%
25%	~69%
0%	50% (floor)

This multiplier scales your gear, talent, and attribute modifiers to damage and mitigation. It does not touch your base level power, raw Health, resistances, or threat — so you never fully collapse, but a drained character is meaningfully weaker on both ends.

Endurance in each mode

Mode	How endurance behaves
World zones	You arrive fully rested on every deploy. Drains per encounter, recovers once per tick.
Raids	Burns per trash wave and per boss. A wipe fully restores health and endurance, so wounds only persist within one attempt.
The Descent	Marathon runs accumulate fatigue over a long descent.

Tip

Because every expedition starts rested, short frequent deploys keep you near full power, while one long marathon run spends the back half fatigued. That is a real strategic trade, not a bug.

Do I need more Endurance or more Regen?

Simple test: estimate a typical tick's drain (four commons = 12; a rare-heavy tick can be 30+) and compare to your per-tick recovery (5% of max + Regen). If you routinely finish ticks near empty, your later fights are running at reduced power. Fix it by raising either:

Endurance (max pool) — a bigger buffer so you never bottom out, and a bigger 5% recovery.
Endurance Regen — more topped up each tick, best when your pool is already healthy.

Tip

Tanks feel this most: they take the most fights and want to stay near full so their mitigation never sags. Fortitude pulls double duty here — it raises your pool and your survivability.
