So we were doing a delve the other day and on the final quest (fighting against Merrik and Elisa Farrow) our Hexer envoked enfeebling hex on Merrik (with 3 hp left).
Merrik was instructed to 'spot' the closest hero, who was 6 spaces away. So he took one damage from the Affliction (to start), then one additional movement for each space moved trying to get into range 3.
Now the Delve rules state;
• If an action would cause a monster to be defeated before it could otherwise affect a hero, skip that action.
But since Merrik had to declare his move action before Affliction could be triggered, that was not an option.
We played it such that Merrik moved himself to death.... but should we have stopped the spot movement action at 1 hp?
