1) If an investigator is delayed in an OW, and is returned to town (by mythos card perhaps). Is he still delayed the next turn? I'm having trouble inventing a situation where it would really matter, but I swear I thought of one earlier. I've guessing he would be.
2) Can an investigator cast wither before moving into a monsters square? I've had situations where I've failed the lore check to cast the spell, and then had to evade a monster, could I have casted the spell before moving and avoided the wasted turns?
3) Wither lasts until the end of "this combat". What exactly is "this combat"? If I'm in a space with 1 monster and I cast it, I use its bonus on all my attacks until one of us is defeated. At that point combat ends, and the bonus is gone (right?). What If i enter a space with 3 monsters and cast it? Is the bonus only applied on the first monster i choose to fight (and defeat?)
