At young age and older, a magma dragon’s bite attack deals additional fire damage equal to its age category.
Three times per day, an ancient or older magma dragon can breathe a cone of lava instead of fire. The damage is unchanged, but the magma clings to those it damages, dealing half damage each round thereafter for 1d3 rounds. After this magma cools, it crumbles to dust.
Environment any mountains or underground (Plane of Fire)
Temperamental and prone to violent outbursts, magma dragons are regarded by most other dragons as dangerously insane—an assumption that, more often than not, proves correct. One can rarely predict a magma dragon’s state of mind until it either attacks or attempts to engage in conversation. For their part, magma dragons can justify all of their actions—they just rarely feel the need to do so.
