You need a level 10 Town Hall to advance your military rank to General. You need to be ranked General to advance your title to Earl, Marquis, etc. Since you cannot advance without a level 10 Town Hall your first Michelangelo script should be used for TH 10. Otherwise TH 10 is probably not as important as Walls 10. After the first TH 10 use your Michelangelo Scripts to create level 10 walls.
