Have no built bonus units should I 5* him especially with his new refine. I'm only tier 18/19 btw
Refining his weapon (I wouldn't give him TA effect, stick with either Attack or Defense refine) and giving him Brazen Atk/Def gives him 14 Attack and 14 Defense when below 80%. While he doesn't have the ability to merge, that attack and defense stat is not to be laughed at. So yeah, I'd promote him.
With a healer or psudo-healer (Micaiah's Sacrifice) you can keep him up without worrying as much about green and reds. There were a few times of where I'd have to go up against an Effie or Hardin with Alfonse and that wouldn't of been possible with TA. With his attack and defense boost he won't have that hard of a time handling physical greens.
I went for TA refine and Swordbreaker, but gave him Fury and QR seal. For his special I actually left Sol from when I was PvE leveling him, which makes it easier for him to see multiple rounds of combat on the enemy phase. It works out well because he can take on every green and sword, and I find he really doesn't need a damage special to do his job.
In tier 20, and now 21, I'm able to easily get 2-3 kills with him per match. This build may be harder to pull off in lower tiers, where people still run mobility skills, cavalry, and dancers.
I did a Res refine so he saves damage from dragons. Finally got my first Ares, so I may be giving him Brazen Atk/Def for A as well. He did fantastic last week, and was no issue this week.
Definitely 5* him, definitely refine his weapon. If you aren't super serious about getting to tier 21, go TA. If you want to get to tier 21, pick your preferred stat (Def/Res recommended over Attack/Speed). He needs the stat grade to upgrade the base effect of his weapon.
My set for him is TA refine, Brazen Atk/Def, Swordbreaker, Aether, and Heavy Blade seal. With the bonus hero boost he gets, and my Sigurd possessing Atk Tactic, he holds 61 with tactic, before Brazen. That's enough to reliably activate Heavy Blade on many opponents. For his C skill, Spur Atk, and a dual rally for his Support Skill. It's Thursday and I'm currently number 1,934 out of 2,807 to get T21, and in most battles, I could only get 2, maybe 3 KOs with him, and a few, I could only get 1. Point is you dont need to have your bonus unit kill absolutely everything to keep your tier high. Although admittedly it is fun to watch him Aether a weakened blue unit to death, especially when he's holding a TA refinement.
