Elderspire is an auto-battler roguelike of cosmic dread that runs entirely in your browser — nothing to download. You play a lone seeker climbing a spire of nightmares, binding the eldritch things inside it into a team of your own and turning their dread against the next horror up the stairs. Here is how a climb works.
The climb
A run is an ascent. You move across a branching map of nodes, choosing your own path upward floor by floor. Combat resolves itself — you build the team and the synergies, then watch your creatures clash. The depth is in the preparation, not in twitch reflexes.
The map and its nodes
Draft — recruit a new creature into your roster.
Omen — a strange choice with a boon or a curse attached.
Shrine — mend your team before the next descent.
Cache — claim an item to reshape a build.
Guardian — the looming horror that gates the way upward.
Recruit your team
Captured horrors come to you as containment dossiers. Draft the ones whose affinities and synergies fit your plan, bench the rest, and reshape your roster as the tower throws new threats at you. Start by meeting a few of them in the bestiary.
Read the matchups
Every creature belongs to one or two of the nine affinities, each strong against some and helpless against others. Stacking the right affinities also unlocks team-wide synergies. Learning the ring is the single biggest thing that turns a doomed run around.
Evolve and adapt
Survive and your creatures grow — learning to wear stranger, more terrible forms. Items, mutations and the dread boons you accept along the way stack into builds that can break a run wide open, or quietly doom it.
Ascend
Reach the top and your team joins The Ascended — a hall of those who conquered the spire. Every creature you encounter is recorded in your bestiary, and finishing runs unlocks new ways to climb.
First-run tips
- Pick a starter and lean into its affinity — a focused team unlocks synergies faster than a scattered one.
- Read every matchup before a fight; a single super-effective hit decides more than raw power.
- Don’t hoard healing — spend it before a Guardian, not after a scratch.
- Weigh every omen. The spire’s gifts always cost something.
