Classes are verified; class details are not
Roblox's public metadata recently showed Raise Your Shadow Army [W6 & Classes], and the current API check now shows Raise Your Shadow Army [PVP Update]. That is enough to keep class questions covered as a recent verified system signal, but it is not enough to publish a best-class tier list, unlock table or effect numbers.
Treat this as a source-watch page until Studio Cochi, the Roblox description, an official event surface or reproducible in-game evidence confirms class names and effects. Use the updates page for the current update state, the PVP Update page for PvP-specific evidence and the army guide for non-scored team planning.
