Couden't agree more with you, currently the hardest/2nd hardest amulet in the game is totally useless.
In order to obtain the 3rd age amulet you have to defeat these monsters below, and it's dropped with a drop rate of 1-1000 (atleast that is what the wiki says)
Revenant orcs
Revenant demons
Revenant hellhounds
Revenant cyclopes
Revenant werewolves
Revenant vampyres
To be fair i see the Revenant monsters almost as hard as kalphite queen it self, and i think you should be awarded for risking gear out in the wilderness.
So to the point. The 3rd age amulet should be great for defense and eventually be made a hybrid necklace just like the amulet of glory, but abit stronger. Stat wise i would go for +10 in each attack bonus and either the same amount of defence bonus as the Amulet of glory (T)
I would also like to see the Fury (T) get a use instead of just being a cosmetic item.
Just as the Amulet of Strenght, Amulet of Magic and Amulet of glory have improved versions of themselfs, However, i know this amulet would prob be really strong, but afterall it's a Amulet of fury (T) Shouden't it be strong ?
