Round 203: Maod chomps on a few cinders, but not nearly enough to have an effect on the cube. Meanwhile he burns his tongue for 17 points of damage, but his snout doesn't catch on fire (32 Ref save).
The cube of fire attacks Maod from all sides, steaming up the water as it moves into Maod's space. Maod's body immediately heals the cinders' physical attacks (DR 13+), but it gets singed again by the heat to the tune of 13 points of damage and catches on fire (19 Ref save). The fire causes another 2 points of damage.
Maod starts round 204 after bleeding for another 6 points of damage. He has 169 hp left and is not hopelessly distracted by everything happening to him (35 Fort save). He will have to concentrate harder to perform any magic use, however.
