I currently have the empowered Apexis cape(695) which gives +229 mastery, i cant remember the int or stamina it gives and i can't seem to find a link to it.
I opted to use the 715 cloak i got but i can't help but feel like i should be using the 695 cape as it gives 6% more mastery, although the 715 cape has higher int etc.
I will obviously be using the cape that drops from Kilrogg when i manage to get it but until then i feel a bit stumped as what to use.
