Final Strike( Savage Species, p. 34)
Your death throes are destructive.
Acid, air, cold, earth, electricity, fire, or water subtype,
When you are killed (that is, when your hit points drop to -10 or lower), your body explodes in a final strike a blast of elemental destruction according to the table below. Everything within 60 feet is subject to the effect. Your final strike deals 1d6 points of damage per Hit Die, up to a maximum of 20d6. Each creature in the area may make a successful Reflex save (DC 10 + 1/2 your Hit Dice + your Con modifier) to halve the damage dealt. The blast also has a secondary effect, which can be reduced or negated (as shown on the table below) by a second successful save of the type indicated (same DC as the save against the primary damage).
|Subtype||Primary Damage||Secondary Damage|
|Acid||Acid||Blindness for 2d4 rounds, Fortitude negates|
|Air||Blast of wind (bludgeoning damage)||Destructive harmonics (1d6 sonic damage per 2 Hit Dice; Reflex half)|
|Cold||Cold||Ice shards (1d6 piercing damage per 2 Hit Dice; Reflex half)|
|Earth||Blast of rock shards||Earthquake (as spell, Reflex save according to effect)|
|Electricity||Lightning||Thunderclap (1d6 sonic damage per 2 Hit Dice, stun for 1 round, deafen for 4d6 rounds; Reflex half and no deafness)|
|Fire||Fire||Light blast (1d6 damage per 2 Hit Dice; Reflex half)|
|Water||Blast of water (bludgeoning damage)||Drench (extinguish nonmagical fire automatically, or magical fire as dispel magic cast by a sorcerer whose level equals your HD total)|
