Can i use more than one Enchantment?

It only goes to the amount of stars stated (so no)

That sucks

Also seeing that i'm using a 5 star it will still be the same att gain as if i was using one enhance at a time? Or is their a set gain when using these scrolls. Cause the results when you use aee vary doesn't it?

For example 5 star gives +10?

Also will it be better to just do single aee for more attack or is the 5 star the best route. Less wards needed
