Abaddon's Prowess (3.5e Invocation)

''The fighting skill of Abaddon is hard for anything to compare to, for it is he who brings the final end to all things. Through him, you also gain the ability to bring destruction to those who dare stand close to you.''

If applied, this invocation removes the 'one per turn' limit on your abyssal blast's proximity blast option. Until the beginning of the next round, you can make iterative attacks with your proximity blast, and even make AOOs with it if you choose. Note that if you apply an abyssal essence invocation to your abyssal blast, you must also apply the same abyssal essence to all other blasts you make this turn.
