What are you people carrying that weighs so much?

Scrolls and accessories are weightless. Only need one set of armour for each character and 1 set each for melee and ranged. Special ammo, potions and food have weight but you don't need a load of this if you are careful in combat. Thieves tools and trap disarm kits seem to easily multiply for me but you don't need to carry many at all. Sell everything you don't use, send extra potions and things you may use later to camp.
