Rules behind the cards
Amplifiers begin at zero: amplifier 0 is level I and amplifier 1 is level II.
Two copies of one named effect do not simply add levels and durations together.
Milk clears all removable effects; honey targets Poison without wiping the rest.
Strength, Weakness, Haste, replacement behavior, and exclusive effects can differ between Java and Bedrock.
Effect questions
Status effects look simple until levels, replacement, undead inversion, editions, and the new omen transitions interact.
Command amplifiers are zero-based. Amplifier 0 creates level I; amplifier 1 creates level II.
Not by simply adding every copy. A stronger or longer version takes priority according to effect rules; Java can preserve a hidden weaker effect on some entities, while Bedrock handles replacement differently.
Milk clears all removable status effects. Honey removes Poison specifically, which lets other active effects remain.
Bad Omen now converts to Raid Omen when entering a village. Raid Omen provides a 30-second preparation period before the raid starts; trial spawners instead convert it into Trial Omen.
