I'm back to life and somehow decided to make this mod, one that I wish it is like this in the original game.
Goal:
Remove limit on Dawnguard Rune Axe and Stag Prince Bow. make them able to level up as much as you like.
the Dawnguard Rune Axe and Stag Prince Bow are interesting weapons, but it has their limit.
what if they level up as much as you want?
this mod does exactly that.

SKSE Required!!!

***Use the loose file version if bsa crash the game.

I did not touch any of the original weapons, those will still behave the original way.
to craft those added weapons, simply obtain the weapon(e.g. the dawnguard rune ax), and go to the forge with the weapon inside your inventory.
Details:
Dawnguard rune axe/Undead Slayer enchantment: 5pts initial damage, unlimited level cap(up to max of long:2,147,483,647)
Stag Prince Bow: 5pts initial Health + Stamina Boost, unlimited level cap(up to max of long:2,147,483,647)

Leveling Curve:


Known Bugs/Limitations:
when you apply undead slayer enchantment to a ranged weapon (bow/crossbow), there is a chance of miss fire due to the way the enchantment is applied to the target. if the weapon's damage is high enough to kill the target without the enchantment triggering, the effect might miss fire.

If you got any other suggestions about more leveled enchantments, leave a comment and I'll consider adding it when I see it(rarely check this site) and got time for it(unlikely) :P

Disclaimer: I do not and will not have SE installed on my PC. most of the time original mods should work in SE.
