The royal shirt is possible loot from a kingly impling jar. It is part of the royal set, and serves a purely decorative purpose. It has no defensive bonuses. In the first weeks after its release it was considered a very rare loot from kingly impling jars. After a period, the Royal shirt, (along with all the other Royal items except for the royal crown) became buyable on the Grand Exchange. The royal set was released on 22 February 2010, accompanying the release of the kingly impling. The kingly impling requires level 91 Hunter to catch. Kingly implings may be found at Puro-Puro and throughout RuneScape, mainly in jungles.
