This is what you want to read!
Apparently, they’ve been adapting the Tonics for use with the costume brawl.
Even better, they’re making it so that they’ll still be useable for that purpose, even after Halloween!
Here’s the relevant bits:
The animal tonics from Black Lion Chests already out there will include brawl skills so anyone with keys from playing their personal story or looting monsters can participate! Mystic tonics and animal tonics are all included. The Boxing Gloves, Cook’s Frying Pan, Pirate Wooden Sword from the Gem Store will all be updated and tweaked to work with Costume Brawl.
Halloween costumes will be unavailable to purchase once Halloween is over, but the brawl will continue to work and the fun will go on with existing costumes and tonics.
Goal: To have one character of every race, gender, and armor class combination at level 80.
Current progress: Human 4/6 | Charr 1/6 | Norn 1/6 | Sylvari 1/6 | Asura 1/6 | Total: 8/30
