In a multiplayer game, if a spell says 'each opponent loses 3 life,' does each opponent independently lose 3 life or is it split?

When a spell or ability says 'each opponent loses 3 life,' it creates an effect that applies individually and independently to every opponent. Each opponent loses exactly 3 life — the total is not pooled and then divided. This is governed by CR 722.1, which explains that effects using the word 'each' apply to every applicable object or player separately.

This means in a four-player game, if you cast a spell that says 'each opponent loses 3 life,' you cause a total of 9 life loss across the table — 3 from each of your three opponents. No one gets to 'share' the burden.

This is different from spells that say 'divide X damage among any number of targets,' where you explicitly choose how to split a total. 'Each' phrasing never involves splitting — it replicates the effect per player (CR 722.2).

Example: You cast a spell reading 'each opponent loses 3 life' in a four-player game. Opponents A, B, and C each independently lose 3 life. Opponent A going to 1 life does not reduce the loss dealt to B or C in any way.

Similarly, any replacement effects or prevention effects that apply to one opponent (such as a 'prevent the next 3 damage' shield) only affect that individual opponent's loss — they do not reduce the loss applied to others (CR 614.1).
