Rare drop table

The rare drop table or RDT is a special list of items. When slain, some monsters have a chance to give loot from the RDT instead of loot from their own unique drop table. This chance usually ranges from 1/16 to 1/64. The RDT is shared by many monsters - examples are chaos druids, lesser demons, most Slayer monsters and the Kalphite Queen.

The RDT contains a main table, with 128 slots. This table has two sub-tables, the Gem table, and the Mega-Rare table. The Gem table has a weight of 20/128, which contains mostly gems but also half keys, rune javelins, chaos talismans, and nature talismans. The Mega-Rare table has a weight of 15/128, and contains mostly empty drops, but also rune spear, dragon spear, and shield left half.

A ring of wealth removes the "empty" slots on the Mega-Rare table. Therefore, the odds of receiving a rune spear, dragon spear or shield left half is increased. A ring of wealth does not affect how often the RDT is accessed.

Using this information, it is possible to calculate the odds of a monster with access to the RDT dropping a specific item if the chance of them rolling the RDT is known. Fire giants have a 1/128 chance of rolling the RDT and the chance of a dragon med helm from the RDT is also 1/128; this effectively means fire giants have a 1/16,384 chance of dropping a dragon med helm.

Free-to-play players have very limited access to the RDT; they can only get uncut gems.

At current prices, the expected value of a drop from the RDT (assuming no ring of wealth) is approximately 9,331.74 coins.
