Simple RAW Thread for 3.5 #36: The Triple Dozen

[Troacctid]

Q141 (I think?): Are there any feats to boost eldritch blast by gaining extra blast shapes, etc if you only have access to a plain eldritch blast? I potentially have access to it without taking warlock, and I'd like to see what I can do with it.

There aren't any feats that can give you blast shapes or essences if you don't already have lesser invocations or better. However, there are prestige classes (enlightened spirit) and magic items (rod of eldritch power) that can do so.
