Yesterday, I did two Centiskorch (four star) Max Raid Battles while trying to find a TR for a good fire move. After doing both, I got the same TRs. I was wondering if the rewards, or at least the TRs, are set and if they are is it a permanent thing, daily, weekly, etc?
I definitely got overheat and I believe I got flare blitz as well. If the exact TRs are deemed to be necessary to answer the question, I will check them later tonight and add them to the question tomorrow.
