Buff calculator

Placement planner

Put towers on the real build spots and see who lands inside a buff radius — and by how much their damage, range and attack speed actually change.

Card level

Periodic buffs are scaled by uptime — duration divided by cooldown. Permanent auras count in full.

Spot

Tier

No towers match the search.

Keys: 1 / 2 / 3 — tier, Delete — remove, Esc — close, Ctrl+Z — undo.

Spot positions come from the scene grid: 8 × 6 tiles of 0.8 world units. The arena artwork behind them is aligned to that grid by its own tower pedestals, so the icons sit on the platforms you see in game.

A buff zone is an ellipse, not a circle: the game measures vertical distance more strictly than horizontal (semi-axes are the range and the range × 0.75). The ratio comes from in-game measurements — the game data does not carry it.

Fit the artwork

Nudge the numbers until the platforms on the artwork sit under the spots, then run the command below to store it. The values also live in the address bar, so the link keeps them.

Buff sources

Click a source to show only its links. Each source has its own colour — the dots on a spot show which buffs it receives.

None of the placed towers grants buffs. The ones that do are marked in the tower picker.

A range buff also widens the aura of the tower it lands on: the Crossbow Fort pushes out the Bastion's Royal Edict. Verified in game on the Bastion; extended to the other abilities by analogy.
