Hey guys,
I did a yolo summon a minute ago to get Jaffar. For some stupid reason, I got him from my first orb (+spd -hp) and then I just decided to finish the session, because RNGesus must have just smiled upon me and got Delthea which is +spd -atk, which is ultra mediocre.
I already have Delthea with +def -spd which is even worse, so I was thinking about a merge. Merging gives her atk and hp and would mean losing 3 points in attack and def, but gaining 6 points in speed. I know that it's quite stupid to ask if it's worth it this way, but thanks to B tomebreaker, the current Delthea never really cared about speed and she could kill most red with one shot, so her attack was her most important stat for me, which is why I would be kind of afraid of losing even just 3 points in it.
PS: foddering one of them for drive atk (which is quite a strong skill) is also an option I guess, but not really my favorite, because Delthea is probably my most used mage, since she makes brave weapon users (and many other heroes) into complete monsters and she can also fight on her own, so making her just slightly better seems like a better way to go.
