No Super Pistol sound for Mesmer
Phantasm uses its own pistols, not pistols based on what the player is using, so I don’t think that should have the SAB sound effect on it. Wouldn’t really make sense.
Magic Bullet definitely should if it doesn’t already, though. It may have the sound effect but just be masked by the fairly loud and distinctive sound that Magic Bullet already has attached to the skill though, I couldn’t say for sure.
I know that “The Prestige” (torch) also has its own distinct sound effect, and that sound effect seems to mostly overshadow the SAB sound effect, though I “think” the SAB sound effect still happens as well.
