Open geodes in the Geodeon
Each geode bursts open in lightning and light to reveal your new Gemkin, from 1 to 5 stars. One at a time or ten at a time, with the odds shown before you open it.
Start from zero
A turn-based RPG for Android. Open geodes, fuse Gemkin and take on four bosses.
Android · Closed beta on Google Play
Late to the party?
If you got into summoning games late, the veterans feel out of reach. STRATUM ZERO is built so they aren't: the edge of those who have played longer, or paid more, has a limit.
- 20 Gemkin species
- 132 fusions
- 4 bosses
- 13 chapters
The game
Fuse two Gemkin into one
In The Amalgamator you merge two different species into a new creature, and the fusion can't be undone. 132 fusions, each with its own name, body and skills.
Turn-based battles, 5 vs 5
Whoever fills their speed bar first acts first. Earth, Water, Air and Fire beat each other in a circle. Play by hand or on auto, at ×1, ×2 or ×3.
Runes in the Runetron
Six runes per Gemkin, 16 sets and upgrades up to +12. Compare before you swap and see how many pieces each set still needs.
Raise stars in the Ascension Spire
Use spare Gemkin to raise another up to 5 stars. If they are the same species, its skills level up too.
Four bosses, each with a trick
Break Amberhorn's plates, burst the bombs that heal Tidetusk, stop Stormcrest before Skyfall and outlast Kilnback's Eruption. Five threat levels in every dungeon.
The story: The Inward Road
The Ravensworth family dopes its Gemkin to grab the best geodes. 13 chapters across three acts and three difficulties. If you only want the fights, turn the dialogues off in Settings.
Fair play
- Losing a battle never takes away Gemkin, runes or items.
- No ads.
- No Gemkin or rune is pay-only: what you get from paid geodes and packs can also be earned by playing, just more slowly.
- Geode odds, shown before you open or buy.
- A clear notice before every real-money purchase.
- Your progress is saved on the server, not just on your phone.
