Skeletal Arsonist does not benefit from some support gems.

Skeletal Arsonist seems to not benefit from some support gems that can be linked to it.

For example "Primal Armament" and "Martial Tempo" can be linked to Skeletal Arsonist , but they do not seem to increase its weapon damage (bouncing bomb) in any way.

And the Skeletal Arsonist definitely is using an actual weapon of some kind since increasing its spell casting speed does not improve its weapon DPS output.

Thanks for looking into this issue.
