Where to go next w Scarlett and why, many thanks in advance

Health attack. Heroes that are so unbalanced between attack and defense should advance with their best stat.

I agree. No matter what you do, Scarlett will still be a glass cannon. Best to increase her attack at every chance and make her attack as powerful as possible while she is alive.

Left path. Mana bonus is nice for an already fast Scarlett, but she needs to improve even more her attack (no matter how you improve her defense, she’ll remain fragile, so… at least make her attack even more).
