Rs gold and items sharing with lootshare feature will help you and your partymates to create a strong bond between each other.
Coinsharing and rs gold sharing for all
Just like other games like world of warcraft, ragnarok online 2, firefall and other MMOs; there are lootsharing feature that enables a party to share a loot. If you don’t need the rare that has been looted by your partymates, you can either “greed” or reroll so that others can have the item they need. Its being polite if you give the items to others IF the rare is NOT compatible for your class.
In runescape, there is a coinshare that can equivalently be divided to the partymembers especially if you have defeated a boss monster. It will give s rs item shard that can be sold in the Grand Exchange and the price of shards will depend on the players. Jagex added 60 items that will be affected by coinshare that will turn into item shards.
