Just a week ago, Jagex released cool looking alien-like armour which is called Sirenic Armour. This armour is a level 90 high leveled ranger type which can boost the stat for Ranger skill and at the same time increase the defense stat in order to withstand any hard hitting damage from monsters. They are made from Sirenic scales which are drops from monsters and creatures in the Monestary of Ascension. Due to this, it can also be said it is a good source for Rs gold sell.
