Level 1: The One Ring - Frodo puts on the Ring and becomes invisible. The Ring weakens him after a certain time. After a while a neutral Eye of Sauron will find him and force him to take the Ring off.
Frodo can receive only one upgrade:
This upgrade can be applied to him through Galadriel's ability Gifts of Lorien.
Frodo can be used as a support hero while throwing rocks. With the ability Phial of Galadriel he can make enemies flee. He can become invisible to escape enemies with the ability The One Ring. These last two abilities should be used one after the other.
