Prestige determines Rank; raising Rank also requires a high position in the server's Rank Ranking. The guide author earns ~250,000 prestige/week: ~100,000 from Shrine offerings, ~150,000 from boss hunting (boss hunting carries the bigger weight). Offering method: 6+ gem-paid offers/day (25/50/100/100/200/200 gems, resets daily) plus Monarch Talent 'Offering' for +20% (max monarch Lv5), plus saving 20+ free Tributes and spending them all at once weekly (ideally just before the Sunday Rank Ranking reset) - prestige per offer maxes at the 16th offer (+500 each, 1,500 gems). Tributes come from Relics (best/free, 25-fragment tile breaks), Alliance Shop (10,000 points each), Black Market (300 gems/5, 500 gems/10). Boss hunting: kill Lv4+ 'Normal' bosses for 120-500 prestige each (Lv15 Phoenix=500 max); most Event bosses give only 50 (same as a Lv1 Zombie); normal roaming monsters cap at 65 (Lv40 Scythian Knight); Viking event nets 2,260 (Easy)/2,996 (Normal)/3,730 (Hard) prestige for 50 kills, comparable to killing 10 Lv7-10 bosses.
