Repeated Subduals should no longer result in the unequipping of items and the removal of packs. That is the relic of a different era for EFU that has little bearing on present circumstances. Today, it only results in unintended side effects from hordes of summoned monsters or spells with staggered damage. If repeated Subduals do still need some aspect of brutality, automatic unconsciousness or ability score penalties until next rest would be superior options.
Nothing like the fear of unintended pack Tetris to keep you on your toes.
