Round 348: Pheto dodges the cloud (Ref save 21), steps back 5 feet, and casts Fire Shield.
Round 349: Pheto is engulfed in 60N50E (natural 1 Ref save). Pheto is not blinded, and gains 4 temporary hit points from the heat. Pheto is at 63 HP. The cloud takes 6 points of damage from the contact and 14 from the Fire Shield, leaving it with 7 HP.
Pheto escapes from the cloud to 60N45E.
Round 350: Pheto avoids the cloud. Pheto hits twice with his falchion, dealing no damage with the blade but dealing 6 fire damage. The cloud has 1 HP remaining.
Round 351: Pheto avoids the cloud. Pheto hits once with falchion, burning the cloud for 3. The cloud is dying. Pheto is at 60N35E, and has 63 HP.
Round 352: A hideous, huge creature with the body of a bloated water buffalo, stumpy legs, a long tail with a knob at the end, and a long neck ending in a head resembling a warthog, although much uglier stomps into the arena to 60N105E. It lifts up its head, and sends a thing, green ray at Pheto, hitting (rolled 21 ranged touch). Pheto dies

(rolled 17 Fort save), exploding in a burst of flame, although the flames do not reach the creature. A small, black egg appears momentarily, then is teleported out of the arena.
Next in round 352 for Chaotic Good is a vazalkyon (MM III). It is exactly the same as a phoelarch except it is of the cold subtype, and any heat or fire abilities the phoelarch has, just substitute in cold (eg. Freezing Ray, Produce Icicle).
