Spend alliance points (earned killing monsters) at the Alliance Shop. Two groups: paid Monthly Card Items ($19.99/month Alliance Monthly Card) and free Normal Items. Spending advice: only Tribute is broadly recommended; Normal Items are worth buying only during limited discount windows (random 24h, triggered by tavern activity), EXCEPT Tribute and Truce Agreements whose prices never change (buy anytime). Key prices (normal/discount, alliance points): Tribute 10,000 (fixed); VIP 100 Points 15,000 (fixed); 10/50/100 Stamina 30,000/50,000/100,000 (discount only); 12h Speed Up 50,000/35,000; 3-Day Speed Up 180,000/126,000; Adv City Teleporter 80,000/64,000; Adv Troop March Speedup 50,000/35,000; Arrest Warrant 50,000/35,000; 8h Gathering Speedup 20,000/10,000; 24h Gathering Speedup 45,000/22,500; 1M Gold 160,000/104,000. Weekly Sale: 8h/24h/3-Day Truce Agreements 30,000/50,000/100,000 (fixed). Monthly Card random items (paid): Blood of Ares, 5K Gems, Medals, Historic General Fragments, Tactic Scrolls. For a bot, buy Tribute and Truce Agreements freely, and grab Stamina/speedups/teleporters only when discounted; alliance points are best held for those discount windows.
