Auto-Run is active as long as there is a running icon near the mini-map.
When exploring massive places, it is recommended to use Auto-Run. This way, you can do other activities while your party leader automatically walks towards your chosen direction. Just make sure to steer his path now and then.
The Auto-Run makes the party leader move in a straight line, which is useful for exploring wide and open areas. It can be canceled if you steer without pressing forward, target an enemy unit, or when your party leader takes aggro from an enemy unit.

There may come a time when Shulk isn't the best leader to use. Such examples are areas infested with Nebula type enemies that are weak to Ether based attacks. Changing your party leader to a character that can dish out Ether damage (Melia) can often prove more beneficial for your party.

Mumkhar is a humanoid boss fight, but he is also a mechon. Using the Monado Art Enchant is necessary for your allies to be able to damage Mumkhar. He has a rank 4 talent called Fiery Pain, so having your shield to rank 4 during this battle can prove helpful. Another thing to watch out for is Mumkhar's Corner, which makes him invulnerable for a few seconds. Hold off on using arts during this time and wait for Corner to dissipate.

Mumkhar is greatly vulnerable to topple and daze. With no allies to support him, focusing on toppling and dazing him with chain attacks and arts will work well.
| | | |
Mumkhar is vulnerable to topple and Daze which Shulk and Reyn are good at. If your party is capable of dealing huge damage, then replacing Sharla with Dunban can be considered if you can topple lock him, and the affinity between the three is high for more chain links.
