The next time someone attempts to seriously do me harm, cast shield, dragonskin, and haste on me.
"Wait a second, my AC just went up by 15.. My new AC is 44."
Or alternatively, try this.
The next time someone attempts to seriously do me harm, cast improved invisibility, ghostform, and teleport me 100 ft forward and to the left relative to my then position and orientation at a 45 degree up angle.
This grants you immunity to non-magical weapons, 50% miss chance from total concealment if your opponent can some how track you to your new position, and an additional 50% chance to ignore any successful attacks from corporeal sources (save some force effects), in addition to giving you your Charisma bonus to AC as a deflection bonus, renders you invisible to tremorsense, darkvision, blindsight, and normal vision, and places you 100 feet forward, 100 feet to the left, and floating 50 feet in the air relative to the poor fool who is about to have several horrid wiltings or firebrands cast upon him.
