After unlocking a wand for the first time you will need to upgrade it as much as you can to get the best benefit. In order to upgrade your wand you will need wand cores and coins. These materials can be acquaired by multiple ways:
- Playing chapters
- Playing challenge levels
- Opening Wand Core Chests
- Claiming patrol earnings
- Daily shop rewardeds
Do not forget that you can use the salvage button located on the info panel of each wand to reallocate upgrade materials if needed.
