A reflected Lightning Blast ends the caster's turn on the spot (rev 28)

FAQ: 'If this gets FULLY REFLECTED, you lose the rest of your turn and
cannot draw cards (in addition to damage).' When the returned bolt
stuns its own caster mid-turn, their remaining actions end at once and
the end-of-turn draw comes up empty (new turn.drawForbidden flag); the
normal stun still costs them the next turn. The affected player sees
'Your own bolt has left you reeling' in place of the usual spent-turn
slip. Older revisions played on and stored games replay so.
