Stats by game mode

	Classic	Expert	Master	Legendary (For the Worthy)
Life	34	68	102	136
Attack	25	50	75	133
Defense	4	4	4	4
Knockback Taken	100% (High)	90% (High)	80% (High)	80% (High)
Coins	1	2 50	2 50	3 50

The last column is Master mode in a world made with the For the Worthy seed. Its numbers were measured in the game, not computed here.

For one player in a world before Hardmode. Expert and Master scale life, attack, knockback and coins by the game's own multipliers.

Coins: each kill rolls the coins from 80% to 175% of this value, then rarer extra rolls can add more.

In a Hardmode world

On Expert and Master, a Hardmode world raises weak enemies: when attack plus defense plus a quarter of life is under 80 (100 after Plantera), the game multiplies them up.

World	Life	Attack	Defense	Knockback Taken	Coins
Expert, In Hardmode	148	90	8	90% (High)	4
Master, In Hardmode	222	135	8	80% (High)	4
Legendary, In Hardmode	296	240	8	80% (High)	5 60
Expert, After Plantera	148	90	8	90% (High)	4
Master, After Plantera	222	135	8	80% (High)	4

Chance is per kill. Kills for 50% and 90% is how many kills give that chance to see the item at least once.
