The latest versions of the Spartan Weaponry mod (1.16.5-2.2.0-rc-2.) contain config files that allow you to change the damage multipliers for weapon groups, as well as the base damage for weapon material tiers. I would love to see this feature come to this mod and your other add-on, Spartan Weaponry: Ice And Fire as it'll allow a lot more customization for authors in modpacks

Multiple people have asked for this feature mainly for the ice and fire compat mod, but I wasn't able to implement it when I tried. If I remember correctly it was a problem with the Spartan Weaponry API itself.
