Skully(Ship)

Skully is one of the two ships added in the Relics of the Past DLC, the other being Arena blaster. Skully is unique in that all Weapons picked up in the run influence the current one.

Gameplay differences
Weapons picked up carry permanent keywords and can modify weapon stats. These do not change the base weapon. When running out of ammo, you keep the weapon you have, and simply stay at zero ammo. Damage Pickups, Artifact Weapons, and the Artifact Upgrade do not spawn, though damage can be changed in other ways. Most weapons fire the same way, simply shooting a projectile similar to revolver, though the look of the shot varies by weapon. Holy water simply adds 5% damage and max ammo.

Stats
Using the starter weapon as a base, the stats of your ammo weapon are multiplied by what you pick up.

Damage
Separate from Damage%, this simply increases the damage of each shot, which is then multiplied by damage%

ammo capacity
Separate from max ammo, this works similarly to damage vs damage%

Firing speed
Controls how fast shots are fired

Projectiles
Controls how many bullets are launched with each shot.

If you have only two projectiles, they will fire in a v pattern, negating most upsides of having multiple projectiles.

Damage will be split between projectiles.

Pierce
Determines how many enemies a single projectile can pass through.

Shot Speed
Controls how fast shots travel.
