Ring of Wealth
The Ring of Wealth (aka R.O.W. or ROW) is an enchanted dragonstone ring. It is created by using the Level-5 Enchant spell on an unenchanted dragonstone ring. This spell requires Level 68 Magic, 1 Cosmic Rune, 15 Earth Runes, and 15 Water Runes to cast.
Teleports
The Ring of Wealth can be used to teleport up to Level-30 Wilderness, similar to the Amulet of Glory. The teleports available are to Edgeville, Varrock, and Falador Park. These locations are not useful, as there are free teleports to all 3 locations. The main benefit of this item is being able to teleport out of the wilderness while in combat.
Each ring will have 5 charges. Rings can be recharged on the fountain of rune in the wilderness.
Special Effects
When worn, the ring grants a boost to all drop rates on PkHonor. The ring increases drop rates by 12% multiplicatively. This means that an item that normally has a drop rate of 1% would be increased to 1.12% while wearing a ring of wealth.
The following is a full explanation on how drop rates work. Source
For any NPC, there's a list of items that can be dropped (some items can be dropped twice but with different amounts, such as coins). For every entry in this list, there's a certain chance (out of 1000) that it will be dropped on kill. For example, a very rare drop may have a drop chance of 10 (so 10/1000 or 1%).
Whenever the NPC is killed, the server goes over every single entry in the droptable for that NPC and generates a random number between 1 and 1000 (including those 2 numbers). If this number is smaller or equal to the drop chance, the item is dropped with the appropriate amount. In theory, you could kill an NPC and have 10 different items drop in one kill (although this happens very rarely).
If you're wearing a ring of wealth (or have an ex-ex-parrot following you or have one in your inventory), this drop chance is increased by 12%, meaning a 1% drop chance will increase to a 1.12% drop chance, or a 11.2/1000 chance (this is rounded down and becomes 11/1000 or 1.1%). If there's an event going on, then the drop chances for the NPC('s) involved in the event increase by 20%, so an item with a 1% drop chance now has 1.2% drop chance (12/1000). If there's an event going on and you wear a RoW/parrot, the drop chance is increased by 20% + 12% = 34%, then a 1% chance becomes a 1.34% chance (13/1000).
The highest extra drop chance anyone could get is during an event, with a RoW/parrot, wearing a whip of fortune and using its spec on the NPC once = 20% + 12% + 14% + 1% = 47%, so a very rare drop of 1% becomes 1.47% or 14/1000. An item with 1.5% chance then becomes 2.205% (or 22/1000) etc.
