On Robbies SS he was getting 355k def xp\hr(can just call it ranged) on task using momentum, so off task using momentum is probably the 300k xp\hr.
I got about 300k range xp/hour at dark beasts.
And was that using abilities or momentum?
EDIT: Also, he got 427k def xp\hr(can just call it magic), so once again probably like 375k mage xp\hr?
I don't know exactly how much slayer helm increases kills\hr, so my guesstimates are just that.
