A livestream with Mod Simon and James revealed the mechanics of Treasure Trail rewards in detail, meaning the actual chances could be calculated: approximately 1 in 37,128 per item roll for any of the 5 parts of third-age druidic, or approximately 1 in 185,640 for a specific part, per item roll - with an average of 5 item rewards per Trail, this gives approximately 1 in 7,426 for any part, or 1 in 37,128 for a specific part, per Trail completed. For a more detailed breakdown of drop mechanics and calculations, see Treasure Trails/Rewards#Elite.
On the day of release, the whole set cost 245 million coins, 220 million if purchased as a Grand Exchange set.
This is the first Third-age armour set which includes five items. The Third-Age Melee/Range/Magic sets all have four items.
Contrary to popular belief, the third-age prayer set is a magic set and does not offer hybrid defenses. It can be functionally equated to an expanded version of the third-age magic set with reduced defenses to accommodate for the addition of a prayer bonus. However, the set is mainly worn for aesthetic purposes as a demonstration of considerable wealth and its exorbitant price makes it an extremely uncommon sight in both PVM and PVP combat areas.
