Try combat 2, the next day:
Okay, Young Adult Red Dragon's (Female) hoard has been looted by the PC's and she's very angry, waiting for them to cross the 250 foot long bridges she knows they will.
Buff Dragon with Mage Armor, +4 to AC.
Check.
Spot PC's crossing Bridge with Spot roll of a Natural 20.
Check.
Scare the Bejeezus out of the PC's by casting Enlarge Person on self, upping your size to Gargantuan, and looking like a CR 21 Red Dragon.
Check.
While flying towards PC's, Continue buffing by casting, Shield, Mirror Image and, Shield of Faith. AC is now 38 with 5 mirror Images.
Check.
Fly within 50 feet of the party, and Breathe 10d10 breath weapon, which the entire party fails the saving throw on and do 64 points of damage.
Check.
Frightful Presence causes the party Druid, Rogue, and a Cohort Fighter to become shaken.
Check.
Shrug off the attacks of 3 Spiritual Weapons (From items), 2 as they simply can't hit your armor, 1 as it fizzles against your SR.
Check.
Laugh as the Druid's Summoned Greater Air Elemental (With Augment Summoning) misses badly from first attack.
Check.
Fail Fortitude Save vs. Baleful Polymorph by roll a 3 from the Druid in the first round, get turned into an iguana, and die that round, before the Breath Weapon comes back.
Oops.
I feel so pathetic.
I haven't killed a PC since February 2004. The Cohort dropping to negatives was the first since then.
I need motivation. Why should I keep going on?
Should I just give up and turn into a Monty Haul DM?
