Would be nice to have an option to buy intervals of army units (currently you can buy 1 at a time or max). Sometimes I'd like to buy half the amount, but I can't really click one million times in a row.
For the hard badges: Choose Neraine as your hero and Ladon as your beast.
Only put points into agility and power. Max out agility first (30 is the cap).
Feed your beast only dark stones. You're aiming for Beezlebub.
Get Deep Blue (A class) and Grim Reaper (S class) for equipment.
Always make sure to buy an Azure Breeze from the store and use it at the start of each level. You only need dark stones for this build.
