The Adv City Teleporter moves your city to chosen coordinates (vs the random plain City Teleporter). Store price 2,000 gems each -- avoid. Focus on free events: Gather Troops and Crazy Egg. Gather Troops Day 5 Destructive Attack (best, up to 32 pcs): kill other players' troops -- 5,000 kills = 1, 10,000 = 2, 20,000 = 3, 50,000 = 10, 100,000 = 15, 300,000 = 22, 500,000 = 32 (NPC sub-city/BoG/BoC kills don't count). Runs ~once or twice a month for ~a week. Efficient tactic: alliance members reinforce an alliance city, then a weak sub-account attacks and loses on purpose so all reinforcers score. Crazy Egg: 4+/day -- smash 3-hammer Lucy egg -> 4 pcs; activate 8-hammer Isabel I egg -> 2 pcs. Less efficient: Daily login + 7 weekly Shrine offerings -> 1/week; Trade Products Event -> 2 pcs; Monarch Competition Stage 5/5 -> 2 pcs; Viking Challenge lucky drop; Wheel of Fortune lucky; Dwarf's Lucky Apple Blessing -> 10 pcs if lucky. Comment: Gather Troops may have been replaced by War Preparation. Also note the Art Hall Mask Hall reward gives Adv City Teleporter x5. For a bot, collect teleporters free from events and the Shrine daily reward rather than buying with gems.
