Howling Blast (3.5e Invocation)
From D&D Wiki
|Greater; 7th; Eldritch Essence|
This eldritch essence invocation changes your eldritch blast into a howling blast by duplicating the howling winds of Pandemonium. A howling blast deals sonic damage. Against objects, the gale-force winds of a howling blast ignores one-half of their hardness and inflicts full damage instead of half, and it has a chance of blowing away the object at the DM's discretion.
Against living targets, a howling blast inflicts only nonlethal damage, but the target must succeed at a Fortitude saving throw (DC equal to 10 + ½ your effective caster level + your Charisma modifier). If they fail, roll 2d6 and consult the following table.
|2||The target is confused for 1d3 rounds|
|3||The target is cowered for 1d2 rounds|
|4-5||The target is deafened for 1 round|
|6-8||No additional effect|
|9-10||The target is knocked prone|
|11||The target is knocked down|
|12||The target is blown away|
Secondary effects from multiple howling blasts are not cumulative. Instead, the most recent effect replaces any previous ones. This has no effect on other pre-existing effects of a similar nature, however.
