I've been playing for a few days, and I'm majorly stuck. I've followed all the helpful guides on here, but I'm stuck when battling. I don't seem to be able to come out on top.

I've bought all the best armour and health bonuses, but against characters that can heal, I seem pretty useless.

My grief is that if Sedna gets the same items, we've both basically got the same health and armour, but she's also got minions. Thus making everything seem very unbalanced.

What am I doing wrong?
