Bold: Important thing.
Underlines: Defining/unique features
Italics: Is related to interaction between 'phase changes', or when they flow into other moves.
Spin Dash (Hop) (Side-B): (Creates charge data)
- 5-6% constant damage
- Charged by holding B.
- Grounded charge can be cancelled by shield as long as it's not fully charged.
- Has high priority and/or invincibility/dodge frames at the beginning of the hop
- Easier to do spinshot out of this move's charge, either from ground or air, due to the hop.
- Has a temporary attack hitbox that goes away after you go under your starting height
- Has higher air speed than normal jumps.
- Knocks the opponent slightly upwards.
- If you have remaining jumps, can be jump cancelled, allowing you to follow-up with aerials
- Turns into Spin Dash Roll upon contact with ground
- Cannot be cancelled by shield on landing.
- Passes charge and 'remaining jumps' data to the Spin Dash Roll that follows.
Aerial Spin Charge (air Down-B) : (Creates charge data)
- Charged by tapping the B button multiple times (3 times for full damage, 5 for full speed in the Spin Dash Roll)
- Has a multiple hit combo:
- - First hit: 7-11 damage (damage based on velocity - hold forward for maximum damage)
- - - High knockback that can KO at higher %'s (170-180%+ on grounded opponents)
- - Follow-up hit(s): 7-10 damage (don't know what changes it)
- - - Lower knockback similar to side-B's knockback.
- Has higher air speed than normal jumps.
- If you have remaining jumps, can be jump cancelled, allowing you to follow-up with aerials
- Turns into a Spin Dash Roll on contact with ground
- Can be cancelled by shield on landing.
- Passes charge and 'remaining jumps' data to the SDR that follows.
So if that made any sense, I think the Spin Dash Roll and Spin Dash Jump are treated as separate moves that take in charge / 'remaining jump' data from the Side-B or Down-B. Side B's "true form" can really just be the hop, and Down-B's "true form" is the aerial version; The rolling attack is just tacked on to both moves. A grounded Down-B is already on the floor (duh), so it goes straight into the rolling attack.
