The main mode of transportation will be the teleporters in the Eryth Sea. To use them, step in the center light of the circle and you will be teleported. Take note that this will teleport you even in the middle of combat, so you can use it to skip fights.
There are a great number of Nebulas in the area, and they are attracted by Ether attacks. Be wary of them as you starts fights, as your allies using Ether skills may bring them into the battle and cause you to be more outnumbered than you expected.
When you fight the four Kromar surrounding the Transport Worker, they do not respawn when you die. You can simply keep battling them, leaving, then going back if you wish, killing them off one by one every battle.
The Monado cannot hurt Entia, so Shulk will only ever deal 1 damage to the Entia. Switch to one of your other party members instead of Shulk, and make sure he isn't in your party!

 Melia

You can use Shulk as your controlled character, but using Melia as a controlled character is also a good choice, as she can use her Mind Blast Art to remove the Telethia's aura, and she can damage Tyrea as well. The suggestion to use Reyn is because he has a higher health than Dunban, and you're fighting not one, but two bosses. Sharla can be interchanged with Riki in this case as your support.
As Tyrea is a High Entia, she cannot be hurt by the Monado and Shulk only does one damage to her. This is why Melia is a good choice for this battle in his place, since using Shulk makes it a bit tougher.
Tyrea buffs the Telethia, so spreading your party would just be spreading yourselves thin. Additionally, the Telethia can attract your party members, so attacking Tyrea might cause your party to split. Use the Command function and force your allies to focus on the Telethia.
Like other Telethia, the Solidum can use an Art that has you miss every attack. If you are playing Shulk, the Monado's Purge Art removes this effect and allows you to hit it. Melia's Mind Blast will also remove this aura.
