Question about Combat Expertise in an intense high-level encounter:
To simplify there are 6 creatures in this fight. The enemy is a Dragon that goes third in initiative. The Dragon has the feat Combat Expertise (PHB, p. 92).
Initiative: P1, P2, Dragon, P3, P4, P5
Round 1:
- Turn #1 and #2 occurs.
- On turn #3, the Dragon takes a full attack action and it uses the Combat Expertise feat with the action.
- Turn #5-6 occurs.
Round 2:
- P1 attacks and deals damage.
- P2 casts the Final Rebuke spell (Spell Compendium, p. 170). The Dragon succeeds on the Will Saving Throw, and P2 beats the Dragon's Spell Resistance. The Dragon is now dazed (PHB, p. 307) for 1 round but it avoided ultimate death. (Correct me if I am wrong up to this point.)
- P3 then attacks the Dragon that used Combat Expertise.
Because the Dragon did not take an action while being dazed, does Combat Expertise still apply to the Dragon's AC during P3's attack?
