Baal-Pteor’s Razor (legendary chest two-handed sword) adds +5 enc while equipped and weighs zero. Don’t know how having it equipped might function during transfer, however, so it may not be of use to you.
Edit: And I’m an idiot who missed your point about ‘no legendary items’ - please ignore me, I’ll go and hide in a corner…
The in keepers pants and shirt gives each +3 enc ehen crafted with named armourer.
Also bearer pack crafted in grandmaster armour bench adds +6 and do not forget to craft em with the armourer that reduces weight , and add further weight reduction kits for maximum capacity upon transfer…
Edit: Aaaaand u said non dlc … XD…
So i can either enter to craft u in keepers xd or u r right!!!
