I'm playing a Psyker in an epic campaign. Our GM has set up a mission for me to create a force weapon of my own. After completeing this mission I should have sufficient knowledge (items may ne near impossible to get) to create force weapons in the future. I was reading in the Acsension handbook, on the Primaris Psyker page, that the psyker will be given a choice of either a common craftsmanship force weapon or a best craftsmanship power weapon. This lead me to think, "What if I get a best craftsmanship thunder hammer?" Now I ask you do thunderhammers count when it comes to power weapons? If so when I upgrade the thunder hammer to a force thunder hammer I'll have to turn off the power field in order to use its psychic abilities. It has to take the mono-edged stats of its non powered counterpart. For a thunder hammer what would that be? The hammer or the warhammer?
Thanks in advance for your help.
Also if any of you have tried this before I'd really like to hear about it.
