I think boruto's curse mark will give him
1.enhanced speed and strength
2.the ability to absorb ninjutsu
3.access to five elements plus yin release,yang release,yin-yang release plus kekkei genkai for example lava style, ice style, explosion style, and a new element created from wind + lightning or fire + lightning style.
4.momoshiki's chakra avatar(s).
What do u think?
