Escalating Bite: A Derej Cobra’s bite increases in damage every time it strikes. A derej cobra inflicts 1d4 points of damage for its first hit, 1d6 for its second hit, and so on up to 1d12; after 1d12, the damage becomes 2d6, then 2d8, then 2d10. This increased damage potential is reduced 1 die level per turn after combat ends, to a minimum of 1d4.
