Yes, it's worth. He is a great Saber, after all. I want to maxed his skills too if I have LOTS of Proofs.

More or less, if you are aiming for castoria, YES, he's the best saber looper until senji release (obviously grailed)

If you like the character really, really much, YES

If it's just for argonauts supports, YES but only the skills is necessary

If it's jus for an AOE saber, i don't think is worth

@Muhammad Abdul Aziz Habibi well I have 1 hero proof left after his skills

Yes bc he’s based and red-pilled
