Added Barracks Advancement
Soldiers now have 3 levels: Basic, Advanced, and Elite; their health and damage are 1, 2, and 3 times their base values, respectively.
Currently, barracks are advanced by fusing weapon workshops and armor workshops of the same rarity.
For example: Advanced Swordsman Barracks 2 + Sword Workshop 2 + Heavy Armor Workshop 2 = Elite Swordsman Barracks 2
Items sold in the shop will now have a glowing indicator when combined with existing buildings.
Soldier upgrades have been added, unlocked using battle merits.
Existing soldier counter relationships remain unchanged; upgrades will strengthen counters to specific unit types.
