What do you think of my Lukas?

It makes me wish I had a Lukas.
Sike!

Wow...53 def holy hell...looks good to me lol. Maybe QR for his B skill though could be better

He is pretty godlike, but you need 40+10 and Defense +3 to make him a true god.

(He will still die to all the mages though).

Great start. Needs a little improvement still. If you can pull an extra Fjorm to fodder off Atk/Def Bond 3 to him, that's a way better version of Fortress Def 3, raising your attack instead of decreasing it, as long as you meet the pretty easy and consistent condition. QR2/3 would be a great upgrade, as well as Threaten Attack2/3. And lastly, a Close Def 3 sacred seal does better. Then it's just merge as you can and watch him tank all melee physical units regardless of color.
