About this game
One Last Sacrifice is an auto battler with meta progression. Build a deck of creatures across multiple battles. Craft them with Path of Exile-inspired modifiers. Unlock skills in a branching skill tree that shapes your playstyle. Six factions, 70+ creatures, and a perk system that makes every match play differently. Fight 1v1 duels or 8-player elimination tournaments - sync or async.
Your jar is your deck, a collection of creatures that carries between matches. Build it through rituals, or adapt mid-combat by buying from the Vein, a rotating shop that refreshes each round. Craft your creatures with Path of Exile-inspired modifiers to push them beyond their base power. But even your best fighters won't last forever: every creature has stability, and each time you field one, it wears down. When it hits zero, it's gone for good.
Many factions. No fairies. No dragons. Each with their own creatures, synergies, and mechanics. Bloodthirsty imps, soul-trapping assassins, hive-minded gel creatures. Build around one faction or mix and match.
As you gain experience and grow in power, new skills become available. They allow you to tailor the experience of combat to your liking. Yet the Arena's Crowd is never still, hungry for spectacle. Each match starts with a random perk that changes the rules - maybe all creatures deal +50% damage, double trigger on death effects or a boost to your economy.
Pick one of three classes and carve your path through the skill tree.
