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.
