You can only equip one weapon at a time. Once looted or bought, the weapon will be kept even if you restart your run in progress. Weapons can be upgraded to +10 using Soul Shards gained by killing bosses (every upgrade increases Raw ATK by 10% of its starting value and % ATK by 5%).
You need 10 + 30 + 50 + 100 + 200 + 300 + 500 + 1000 + 1500 + 2000 = 5690 Soul Shards to max a Weapon.
All weapons give Raw ATK / % ATK : Raw ATK is first added to your total stats, for % ATK to multiply it all (Base ATK, Raw ATK, bonus ATK from ATK Character, and ATK from Gems).
