Effect

What Regeneration does

Regenerates HP over time.

Regeneration is a level-up pick that raises HP Regen for the rest of the run. Every further pick adds another level, up to 60; rarer offers grant more per level.

Per level

Regeneration by rarity

Gain per level of Regeneration
Common+0.12 HP/s HP Regen
Uncommon+0.15 HP/s HP Regen
Rare+0.18 HP/s HP Regen
Epic+0.21 HP/s HP Regen
Legendary+0.27 HP/s HP Regen

Luck — from Fortune or the Censer — shifts your offers toward the rarer rows.

Fit

Who Regeneration is for

Regeneration acts on your hero rather than on one skill, so it fits every build. Melee heroes who stand in the horde get the most out of it.

Timing

When to take Regeneration

Take it when the horde starts landing hits — usually around the first minibosses. One defensive potion early buys the time your damage needs to scale. Out of slots? The Thorn Archive on each floor’s plaza removes a potion, and the Diamond Trader sells extra potion slots.
