I had a few ideas about your ranged weapons problem.

1) Magic. This is D&D, after all. My simple idea is that the Player with nubs for hands starts with magic gloves that, when attuned, allow the owner to move the glove's fingers. So you put on the gloves and now you can hold things.

2) Tails. Some Pokemon (Not all, I know) have tails. These tails could be used to throw things or used as Pseudo-hands to pull back a bowstring/crossbow or whatnot.

3) Blowguns. Most Pokemon breathe (Not all, unfortunately) and can therefore use a Blowgun. While a Blowgun wouldn't do that much damage, you can still poison the target

4) Magnetism. A few of the Pokemon have some sort of magnet/levitation ability. Why not magnetically/telekinetically shove something away from you at high speeds?


I hope this helps!
