Curve Spike

Curve Spike is a permanent Godly ability, although the wiki records that it used to be Legendary before being promoted. It enhances your next spike or serve so that the ball spins in line with the direction you tilt: a forward tilt floats the ball forward, a back tilt slows it and then floats it backward, left or right curves it sideways, and tilts can be combined. On 2025-03-15 it received a buff that raised spin speed by 100%.

The wiki calls it most useful on serves, because opponents cannot see which way the server is tilting, and advises against forward-tilt curves since the ball usually floats out of bounds. That makes it a fit for serving specialists and for spikers who like to disguise placement, whereas Divine Strength, another Godly ability, adds raw spike power instead of changing the ball path.

Its drop rate is listed for the whole Godly rarity, not for Curve Spike alone. At level 15 and above that is 0.495% on a normal Ability Spin (250 Yen) and 4.75% on a Lucky Ability Spin, and below level 15 it is 0.505% and 5.25%.
