My very first mod that i manage to get to work, just like in the picture above, not only it have over 5000 damage. It also have various cheat as well, except darkvision and damage reduction (only in description) i decide to remove damage reduction because i dont know how it work but instead, the sword grant it user damage immunity to all type of damage (13 in total) and it also grant Superior Darkvision (able to see in the dark up to 24m).

I still learning this mod thingy so no while it use the Everburn Sword physic, my sword didnt have burning visual, now the file contain 2 swords, one is burning while the other is not, so use the one you like. Also, i decide to change the sword name just so not to be confused with the original Everburn Blade. There's two version, V1 have all type of damage on it, V2 only have two type of damage but hit more than V1 as you can see in the picture.

Detail about the sword :
1.Able to dish out 13 type of damage with 20d20 each.
2.Ignore those 13 type of damage resistance.
3.If the target somehow survive after a hit, the target must succeed a constitution saving throw(12d) or else be silenced for 10 turn, silenced target cant cast spell and are immune to thunder damage.
4.Increase your intuition by 20 so unless you're Surprised or disabled by some other means or your enemy have higher intuition than you, most of the time, the sword holder will be the first to make a
move.
5.Grant martial weapon proficiency to the sword holder so you won't get proficient penalty.
6.Grant a spell Weapon Bond.
7.Grant Superior Darkvision (able to see in the dark up to 24m) to the sword holder.
8.Grant Immunity to all type of damage to the sword holder.
