A small clarification to our plans with Mount Equipment–
Hitting level 100 on one character will unlock this system. Once unlocked, the system will be available to all characters, and the equipment pieces themselves will require level 20. If your goal is to have waterwalking while leveling, you can just enable the waterwalking Mount Equipment (there will be one available via Anglers reputation that will be bind-on-account), and it’ll work exactly as before, with the benefit of making all of that character’s mounts walk on water.
