I have an almost maxed Sartana but while trying for Victor, it gave me a 2nd Sartana instead. So should I up her or Aeron?
I would say go for Aeron. He is a fixture of my attack team along with Merlin and Sartana
Go for Aeron without a doubt.
Healer, status protection and elemental link.
I guess he is in all best yellow titan team, as he both cure, boost attack and protect from blindness.
Even his stats are good.
Which skill boosts attack?
The Elemental Link gives a small boost to all dark heroes.
