Treasure/Possessions: Triple Standard
Breath Weapon(Su): A hex dragon has one type of breath weapon, a line of putrid venom. All within the area of effect suffer the listed amount of Constitution damage on failed Fortitude saves. As with normal poisons, another save against the same DC is required a minute later to avoid the same Constitution damage again.
Vile Resistance (Ex): Hex dragons receive a +4 bonus on saves versus death effects, enchantment spells, and effects that deal negative energy damage. They are immune to disease and poison.
Retributive Curse (Su): Hex dragons have learned to channel their pain and anger into terrible retributive magic; many foes who succeed in wounding a hex dragon find themselves wishing they could take back the blow. On any round in which a hex dragon is injured (taking hit point or ability damage), the dragon may curse one of the opponents who injured it as a free action. The effects of this curse increase as the dragon ages:
Sickness: Target is sickened for 1d4 rounds.
Agony: Target is crippled by agonizing pain (treat as nauseated) for 1d4 rounds.
Blindness: Target is permanently blinded.
Insanity: Target becomes permanently confused, as per the spell insanity.
Oblivion: Target is obliterated (as if affected by a sphere of annihilation).
A successful Will save negates the effect. A hex dragon may bestow curses from younger age categories, if it so chooses. The save DC against this curse is 10 + 1/2 the dragon's HD + the dragon's Charisma modifier.
Should a hex dragon ever be killed or mortally wounded (reduced to negative hit points), it reflexively unleashes a death curse against all creatures within a radius equal to 10 feet per age category. All creatures within the area must save as above or suffer the effects of this retributive curse.
Other Spell-Like Abilities (Sp): At will - deathwatch, 3/day - suggestion; 1/day - geas/quest, hold person, mass, wail of the banshee.
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.
