He really could have benefitted from a QAABB deck. As a 1* berserker with a gorilla deck, his damage output does him no favors , and offers no support for his main niche which is neutering enemies with his broken NP. With how DW is updating older servants’ animations and giving them ability or NP upgrades, I really do hope they give him an NP battery or something, because he is long overdue for it.
Might want to post here: Servants who desperately need strengthening
Another thing he could benefit is debuff success rate up.
Missing either of the attack down debuffs, especially in AoE scenarios, can be extremely dangerous since it’s all he has to neutralize incoming damage.
I usually attack with Asterios only after he’s used his NP (Def down on enemies make them soft). Other than that, he’s to be protected by his moms and dads from pain.
If they buff him, nice. If they don’t, meh. Still grailed him anyway
