Banisment damage caluclation?

[Chud]

Out of curiosity, for Banishment (and also Mass Banishment) is the player damage re-calculated for each monster?

In other words, is a separate 1d4 rolled for each monster removed, or is it simply
(1d4) * (monster_count)?

It's a separate 1d4 for each monster (or 1d3 for mass banishment).
