Timeline

This is a timeline mod which shows the timeline of the events that happened in the game. I tried to group things reasonably so there isnt too much clutter of different events on the timeline, and hovering over an event tells you in detail what all happened in that event. Its just a nice thing for keeping track of things. I haven't really tried it on multiplayer much but it should work(I think I had it open for one run but didn't really check)
timeline closed(default)
timeline open(click anywhere on it to open it)
if you have suggestions or find bugs leave them as issues on the GitHub repo and I'll get to them.
The rest of this was written by claude so its probably right but idk:

What it does

• Overlay showing every event in the current fight in chronological order: card plays, attacks, relic triggers, power applications.
• Each event uses the actual game card / relic / power icon (same art the deck-view uses) so it looks native rather than bolted on.
• Hover any event to see the parent (what triggered it) and the children (what it triggered in turn).
• Updates live as combat progresses; persists for the fight.
• No gameplay effect.

Known limits

• Long fights produce a long list. The overlay scrolls but on particularly busy turns it can get dense.
• STS2 disables achievements while any mod is loaded — uninstall if you're chasing those.

Install

If you're using the STS2 Mod Manager, just click install through it. Manual: extract the zip so the folder structure is 
<game>/mods/Timeline/{Timeline.dll, mod_manifest.json}.

• Mac:  <game>/SlayTheSpire2.app/Contents/MacOS/mods/Timeline/
• Windows/Linux:  <game>/mods/Timeline/

Then launch the game and enable Timeline on the in-game Mods screen.
