Epochs & Timeline

Epochs are how Slay the Spire 2 handles unlocks — instead of just playing more runs, each one has a specific thing you need to do. Complete it, get the reward. The Timeline is essentially your checklist for all of them.

What is the Timeline?

Your unlock checklist. Hover an undiscovered Epoch in-game to see what it wants from you.

Accumulate Score

A lot of Epochs just unlock as you play — score stacks up after every run whether you win or lose.

Epoch Discovered

You'll get a pop-up when a new one unlocks. New Epochs also appear on the Timeline as you progress further.

General Epochs unlock through score, cross-character milestones, or encountering Ancients. Rewards here — colorless cards, shared relics, alternate acts, new Ancients — are available to every character.
