That was not made clear in YOUR OP in this thread… Is that what you meant by posting this thread? It seemed you were more interested in general discussion about never seen before builds?
Perhaps this would have been important information to include in your OP. Also of course these have all be thought of as both doom bolt & the warlock class are commonly used…
I guess I should add that I have and use both an acid & physical doom bolts semi-regulalry with great results.
