Flame Blade

I had the same idea, attack 114 is enough because Delita stats already high enough. Do you think it's better to make tanky delita or evasion?

Go with evasion because Basic Hp delita is not high enough even u build him as a tank,and also his TMR or this sword have evasion ability,u can combine those with saint sandals will given ur delita more evasion and Mythirl Armor

Lilyth TMR Flame Blade
Mythirl Armor
Saint Sandals
3 of those is Good when u want to build Evasion unit for Delita
