About Spell Cascade
Every run ends with a title for your build, such as Phantom Executioner, Chain Annihilator or Perfect Cascade. You steer a tower with WASD, aim attacks with the mouse, and hold out against waves of enemies for 10 minutes. The game has 15 build names in total.
Builds come from stacking parts when upgrades are offered, which you pick by clicking. There are 10 skills, including Fireball, Meteor and Void Bolt, plus 8 supports like Chain, Fork and Pierce. 40 attribute mods, split into 20 prefixes and 20 suffixes, change how a build behaves. Ten synergies trigger when the right pieces combine.
Enemies come in seven types: Swarmer, Shooter, Tank, Splitter, Healer, Boss and Phantom. Survive long enough and a three-phase boss appears. Clear Wave 20 to unlock Endless Mode and keep playing for a higher score.
Nine automation chips are kept in a Chip Vault and carry over between runs. The game is marked as early development. The creator is a non-engineer who worked with Claude Code over 235 commits.
