Currently, third age ranger sets are the most expensive ranged armour in RuneScape, ahead of pernix armour. Players wear this set to show their wealth rather than use in combat, as there are other ranged armours, such as royal dragonhide, that have equal or better stats, while also being much cheaper.
It was long thought that the chances of obtaining a piece of third-age armour was of about 1 in 10,000 (according to Paul Gower), and in 2010 Mod Maylea stated that the odds are lower than 1 in 100,000 [1]. More recently, however, Mod John C confirmed that the chance of receiving a specific piece of third-age armour from a Treasure Trail is 1 in 42,000, so the chance of receiving any piece of third-age ranger armour from a Treasure Trail is 1 in 10,500.[2]
