I see u already have angie as the tank & healer so I suggest go for furious, u can give him song of stars for more overall dmg output and extra debuff secured

I would build furious, Furious’s defense break cycles faster, also you get a nice crit chance buff for the entire team.

My wyvern 13 team its: angelica (as tank) ssb, furious and chloe.

Personally I never build tywin, and furious do a decent job there.

clarissa exist u know, the best defense breaker is unit with deff break on basic skill, and its very limited

I used Tywin for a long time, simply because I wanted to use him (was my selective 5* which I still regret), as a tank and defense breaker there. Have replaced him with GP the moment I got the chance.

Now he is in the fire Expe.

So tldr: No you dont need Tywin for it, dont waste your resources on him. He really is not worth it in his current state (he needed a buff a while back already, but after they updated Flann, he completely fell into obscurity).

Personally I dont use Furius coz I strongly dislike that character. Confile SSB and Karin are doing the defense breaking part for me. Luluca or Taranor can also work, but less reliable.

both are bad for best w13 run

just go taranor guard 3*, everyone has him and free, dont ever underestimate tg.

go for Furious, he's free from connection and he has a perfect synergy with a slow RAGE set Sigret.
