Test #1: Turn in 100 trinkets @ level 111: * 24 hits @ 300,000 = 7,200,000 (24%) * 24 hits @ 690,000 = 16,560,000 (24%) * 20 hits @ 1,380,000 = 27,600,000 (20%) * 9 hits @ 2,400,000 = 21,600,000 (9%) * 13 hits @ 3,442,000 = 44,746,000 (13%) * 10 hits @ 6,890,000 = 68,900,000 (10%) Statistically, handing in 100 trinkets should result in 2 levels worth of experience. The rewards are percentage-based, so this holds true at any level (currently unknown, but is at least level 170).
