Arsenal is a special kind of inventory that is used to empower your character in defense in the Tournament. Please note that when you put spells and boosts in the Arsenal they are removed from your inventory and are automatically spent when someone attacks you in the Tournament.
There are 3 slots for spells and 3 slots for boosts in the Arsenal. You can put them in any respective slot but they are spent from left to right. When the most left equipped slot becomes empty, the game starts using the next most left slot.
When your Arsenal is used up, you will receive a notification in your inbox.
You can put 100 units of an enhancer in each slot.
You can also reclaim your spells and boosts from the Arsenal at any time.
