that can be viewed in config.yml.
When a player has PVP disabled, they cannot attack or be attacked by other players despite their PVP statuses.
The PVP status of each player can be locked by admins with the personalpvp.lock permission by default.
Locking a player's status prevents the player from successfully toggling their PVP status while locked.

Projectiles and potion throwing
When one player (or both) has PVP enabled and they try to attack a player who has PVP disabled (or vice-versa), no damage is dealt. If they threw a projectile (by shooting an arrow from a bow or throwing a trident at the player) or a splash potion, the projectile will be returned to the "shooter's" inventory if one of the players had PVP disabled. For this to occur, these config options should be true respectively.
