The “Adjustable Crossbars” upgrade in the Siege Workshop says it increases the Blast Radius of Mangonels by +100%.
However, it actually increases the Blast Radius by only +50%.
Image below shows that the Blast Radius changes from 2 → 3 (meters).
Since 4 meters = 1 tile in-game, that means the Blast Radius went from 0.5 tiles to 0.75 tiles (+50%).
Note: The “projectile spread” also increase to 1.0 tiles, which is probably okay, but the upgrade doesn’t say it does this.
The Season 9 update says this for Mangonel Blast Radius:
Season 9 Update 12.0.1974
Mangonel
- Each boulder’s blast radius reduced from 0.875 → 0.5 tiles.
- Projectile spread reduced from 0.75 → 0.5 tiles.
Adjustable Crossbars Technology
- Effect changed from +25% attack speed to +100% splash radius, +1 range, and +1 projectile added to Mangonel Attacks.
Either the +50% effect is wrong, or the +100% description is wrong.
