Can we make it so ALL godly weapons can be activated for the bonus at least then they have some use and value

Even if they were activateable they would still have no value, the activation bonus only lasts 15 minutes. Not worth the effort of even adding imo, nobody uses them.

then make the buffs different and/or last longer?

I saw one of these weapons, an steel dagger/sword? that had +55 res, I would totally use that even if it was for 15 minutes only

Make it 1hr, all useable by all players, and call it a day

Agree with cloun here. It's not like this would be a lot of work either. Can all be done in CGI, they wont turn into plain weapons like skua/purple do but that would be easily doable if desired with a simple code addition.
