Hallo 

So ive used this new upgraded version of slayer helmet for quiet a few tasks since the update. Ive noticed something strange, when im looking on my max hit it tells me its 35 includeing piety melee. while ive been doing tasks i havent been able to hit above this amount yet. The slayer hit should be supposed to hit Maxhit*1.15 which is 40.25
Therefor ive concluded that there must be something either i have misunderstood or the helmet simply doesent add the 15% damage.
I do get the 15% xp bonus tho

Thanks a lot, the system was indeed bugged. Next update will fix it.
