It is recommended to have Stealth Of The Shire 1 and Courage Of Sam 3 to get past the enemies. If you use it, you will block all attacks on Frodo and Sam. Note: This does not work in Multiplayer mode.
It is recommended that you complete the extra battles that become available throughout the game. By doing this, all of your heroes will be at a higher level when it is time to use them in the difficult later battles.
