Seven ranks Knight->Regent, each unlocked by EITHER prestige OR a VIP level (VIP13-19). Prestige thresholds: Knight 5,000; Baron 20,000; Viscount 65,000; Earl 163,000; Duke 343,000; Archduke 703,000; Regent 3,000,000. Rank buffs (Knight->Regent): Training Speed / Healing Speed / March Speed / Traps Building Speed each +5/+10/+15/+20/+30/+50/+70%; General Capacity -/+1/+2/+4/+6/+9/+14; Subordinate City Capacity +1/+2/+3/+4/+5/+6/+6; March Size Capacity +5,000/+10,000/+15,000/+20,000/+30,000/+50,000/+100,000. Strategy levers: higher rank raises march size, adds subordinate-city slots (more mayors = more stackable debuffs), and lifts general capacity. Duke (+30% training/healing/march, +5 sub-cities) is the common mid target; Regent needs 3,000,000 prestige.
