Vanea will give you a quest regarding 5 Monado Replicas. To complete the majority of these quests. You need to have a level around the high 80's to low 90's which might make the game too easy. |
Note 2 | There will be a spike in difficulty upon reaching the bionis' interior. It is suggested to have your levels reach at least 70 to be able to proceed through the level. But if you plan to do sidequests without making the final battle too easy, a recommended level you should attempt to reach is low 80's. |
6 | Talk to Miqol and ask him to take you inside the Bionis. |
Objectives | |
---|---|
1 | Make your way through the vein crossroad. You will be encountering several Telethia elites on your way to your destination. Their levels are around the mid 70's, so make sure your levels are close to theirs before proceeding (unless you intend to avoid most of them). |

3 | Proceed to the teleporter stationed on the right side of the room. |
4 | Follow the narrow path until you reach the an open area. |

6 | Enter the area where the Demon Pavlosk came from to reveal your next destination. |
7 | Defeat both Sanjibal Behemoth's to proceed. The Behemoth inhabits the same area, but the area itself is quite spacy. The Behemoths can be fought one by one to make the fight easier. |

14 | Cross the Gravina Bridge then climb the stairs until you reach the next teleporter There will be several nebula enemies scattered along the path. You can draft a heavy ether team to dispatch them or make a pure physical team so you won't take their aggro. |
15 | After reaching the Gondorl Cathedral, head forward for a short scene, then head south and climb the tower. Activate the Dragon Summon. |
16 | Use the switch on the left most side of the teleporter to reveal the transporter. This is the point of no return! Avoid going forward if you still wish to do some other activities, or make a duplicate save file so you can backtrack later. |

It might be obvious already at this point in the game, but you can fast travel to previously visited landmarks (except landmarks on the Mechonis due to story events). There will be several sidequests that will become available in Chapter 17, and it is highly suggested to just warp to said locations instead of walking around and visiting each area one by one.
You will be given a quest by Vanea that makes you look for materials to craft 5 different Monados. This is a good time to invest powering Shulk up before heading to the last parts of the game.
This is one of the best ways to spend your time with before ending the game. Rebuilding Colony 6 will unlock several new quests and shops for you to use that can further strengthen your party.
Watch out for Soul Read! Disable the Telethia's Soul Read to defeat it. Aura removal arts is a must-have in this fight. The Telethia can use Ether Particles, which is an Ether-based attack and also inflicts Ether Down. Getting hit with the ability twice in succession will prove fatal to your party.
Shulk | Dunban | Sharla |
Shulk is back in action! He has the best aura removal ability in the game, which is a much-needed move against the Telethia. Just don't forget to equip some gems to Shulk's new weapon. Sharla is also good to have with her Cure Bullet or Cure Round to remove the debuff caused by Ether Particles.
The 2nd Telethia fight in succession. This fight is completely different than the first one, as Sani Telethia won't even use Soul Read to defend itself. It has several area attacks that deal heavy damage to units in front of it. Take note of the weather, Sani Telethia will change it at will and its moves will vary depending on the current weather.
Aside from Telethia Buster VII, which is a physical attack, all of it's other moves are ether types. Thunder Bolt and Bolt from the Blue can inflict paralysis, but there are no notable moves that can cause too much trouble to a well prepared party.
Shock Wave and Thunderbolt.
Splash Wave, Sunlight Scatter, and Thunderbolt.
Sunlight Scatter, Bolt from the Blue.
Shulk | Dunban | Riki |
Not many debuffs to take note of so Sharla isn't a must-have. Riki and Shulk's heal will be enough to sustain your party's HP in the battle. A good chain attack can also end the fight rather quickly.
Lorithia will summon Nova enemies during the fight. Lorithia's defenses will change depending on the number of enemies alive. Reducing the number of enemies to 2 will allow you to damage her while reducing them further will make her take more damage than usual. Build up your party gauge by using Burst Affinities. When a Chain Attack becomes available, dispatch all enemies, then use it on Lorithia to bring her down.
Dunban | Sharla | Melia |
Lorithia will be summoning Nova type enemies, so adding Melia in the party is a must (setting her as your leader will be even better). Also, make sure to add Blaze, Wind, and Ice to your art arsenal, as attacking the Nova with Area attacks will allow you to dispatch them rather quickly.
Have Dunban take the frontline, then have Sharla take the back and equip her with Thunder Bullet to give your party a good way to dispatch the Novas. Fiora can replace Dunban if you wish to do so, but using Dunban's Blossom Dance during a chain attack can allow you to defeat Lorithia with a single chain attack from full health if you destroy all novas and the multiplier is maxed out.
It can use the Talent Arts Annihilation V and Legendary Claw VII. Blocking these moves with Shield is a must, since Annihilation can inflict topple, while Legendary Claw inflicts high damage and can potentially KO all the targets hit. Do not topple Master Obart, as it will activate its, spike abilities which will damage you whenever you hit it.
Shulk | Dunban | Riki |
Shulk is the only recommended character, and the other two depends on the player. Just avoid toppling it and keeping Shield up, and the fight will prove effortless to beat.
A big guy with a counter spike ability. Everytime you hit Dragon King Alcar, you will suffer 450 damage. The way to approach this fight will vary depending on the chosen characters for the fight which will be detailed below.
If you have the necessary materials, crafting spike defense gems and equipping them to your characters will allow you to approach this fight normally. You can get a maximum of 100% spike defense if you have the necessary gems, so you can ignore Alcar's counter spike ability with this setup and just lay havoc on him.
Shulk | Reyn | Dunban |
Alcar's counter spike will disappear if he gets toppled. Utilizing a topple lock party will allow you to beat him up without him being able to counter you at all. This requires a high affinity and high skill levels for your characters, as well as some topple plus gems to be executed properly.
How to Topple | Topple Lock Guide
Shulk | Dunban | Sharla |
The default strategy. Purging Alcar's spike ability will allow you to hit him without worry. Just make sure to keep on reapplying purge whenever Alcar recovers it. Adding Sharla to your team will allow you to avoid accidental death with this strategy.
A two-phase fight. You'll have to bring Dickson's HP down to 50%, then fight him again to defeat him. He has a paralysis spike ability, and is immune to Purge, so using art heavy characters is recommended for the fight. He also becomes immune to topple at low health, so using a topple lock setup might prove disadvantageous in the long run.
Shulk | Dunban | Sharla |
Sharla is the chosen healer in this fight due to dickson's ability to remove debuffs, making Riki's value lower. Sharla can also focus on healing, so paralysis won't be too much of an issue for her. Make sure to position Shulk away from your party to avoid Dickson's Chaos Punish so you can remove the daze from your allies that get hit.
