Idk Ive been thinking about this for a while and figured i may as well throw it out there:
(trigger warning: only equipable after heroes quest is complete, not suggesting 'special' attacks its just a normal rsc weapon)
Dragon Mace :

WeaponAim:65
WeaponPower:59
Prayer:+4
It would have the lowest power and aim of any of the current dragon weapons,but also the only dragon weapon with a prayer bonus.
The point of this would be slower draining prayer in exchange for a little damage and accuracy, it also wouldn't be too useful under 70 prayer
Been thinking about it since hardened rune was released which made a new maximum prayer bonus
Maybe as a slayer drop, or on the vendor with Dragon Axe for around 130k, both even
Also, and again just throwing it out there;
With the release of Slayer it would be really cool to have the Dragon Spear/Dagger as a high level slayer drop.
Dragon Spear

WeaponAim:62
WeaponPower:54
Dragon Dagger(After Lost City, costs 75k at dragon sword vendor)
http://ibb.co/iYJLaQ
WeaponAim:66
WeaponPower:48
The point of these weapons would be the ability to finally add poison to dragon weapons.
It would have even less strength bonus than the dragon mace, making it the new weakest dragon item stat-wise.
The spear would have no quest requirement, but it would require maybe 85+ slayer to obtain. Tradeable of course.
