Raven Elk considers his reply as he watches the beetles approach. Trying at a bit of flippancy, or at least the best he can offer, he answers Adi:
"Flip 'em over and bludgeon them for all you've got, my friend. It worked with the last ones.". He then gives his smirky smile that could be either humorous or sarcastic. Always hard to tell with Raven Elk.
He could have left it at that, but then he can't help but add an extra morsel of "scholarly" info, killing any chance at humor, "Of course, like people, many beetles are very different. These could be susceptible to piercing or slashing.". He then looks at Adi and shrugs.
Raven Elk then waits for the first of the beetles to approach in order to flip one over and then "punch" it with the butt end of his spear.
