On Bob's next turn, he charges Alice. The attack he would take at the end of his charge meets the trigger conditions for Alice's readied action, so she teleports away.
What exactly happens?
- Does Bob get to make his melee attack before Alice teleports?
- Does it matter whether Alice teleports somewhere that would have been within Bob's original charge range, versus somewhere he could not have charged in the first place?
- If Bob doesn't get to attack, does he still lose his entire full round action for charging? Or has he only spent a move action if he never gets to attack? What if he's already moved farther than he could have with a single move action (since you can charge twice your speed)?
- Would it matter if Alice had chosen a different trigger condition for her readied action, like "a creature comes within 20 feet of me?"
