I've been having trouble wording searches and finding info on this. If I were to level up Lord Chrom to level 10, then use a Second Seal to make him an Archer, could I then use a Master Seal to make him a Great Lord from a level 10 Archer or would I have to switch him back to the Lord class and level him up to 10 again because he never was changed into a great lord while in that bracket of classes? Basically, I don't know if getting to level 10 as a Lord itself unlocks the Great Lord as a Master Seal option at any time or if I have to actually make him a Great Lord to keep that class unlocked in the future. Thanks
