Enchanting
Enchantments · From the in-game Encyclopedia Aura.
Six Colors
Red = temporary Silk Touch mining override and suppresses block XP. Orange multiplies harvestable-tool break speed by 1.15 per level. Yellow sets Fortune to its level on non-crop harvests.
Green, Blue, Violet
Green fells up to 25 times its level in face-connected blocks of the same log type, counting the first. Blue pushes attacked targets by 0.5 per level along your yaw. Violet adds 0.5 per level to player-sourced outgoing damage.
Pair Strength
For two colors, pair strength is ceil(sqrt(level A x level B)), including two levels of the same color. See Enchant Matrix for every pairing, and Consumers and Vortex for Enchanter inputs.
Chance to Bind
The first color level always lands. Later levels or colors succeed at three-quarters of the prior chance; taking one color beyond level four quarters the next chance. A failed attempt still consumes its crystal.
