Fusing

How to Fuse
You can't JUST fuse towers together. You need the item card 'Fuse.' Without this card you cannot fuse towers together. Basically you need to have both towers and this card in your hand at the same time, then you use the item card and select both towers.

Pros and Cons

 * Pros - You get a Stronger Tower


 * Cons - Both of the towers you select get used up and can't be used.
