Fellsmoke Blast (3.5e Invocation)
From D&D Wiki
|Lesser; 6th; Eldritch Essence|
By tearing a microrift into the heart of the paraelemental plane of smoke, this eldritch essence invocation allows you to change your eldritch blast into a flamefell blast that deals half-fire and half-acid damage. Since the flamefellfell blast rips through the planes, it affects ethereal and other incorporeal creatures as if it were a force effect.
Furthermore, iIf the target fails a Fortitude save (DC 10 + ½ your effective caster level + your Charisma modifier), they become disabled due to coughing and choking. This condition lasts 1d3 rounds. Targets who do not breath or who are protected from gaseous attacks are immune to this effect.
Unlike its greater cousin frostfell blast, the energy being tapped by flamefell blast is not unusually hot or acidic, and thus has no effect on a creature's immunity or resistance to such attacks.
