Paralogue battles are essentially side missions that typically earn you new characters or release the Bond Level Cap on Emblems. In the case of this particular Paralogue, it’ll allow you to unlock Byleth’s Bond Level cap. This page will discuss how to unlock the The Instructor and once done, how to defeat Byleth in this challenging battle.
How to Unlock Byleth’s Paralogue: The Instructor in Fire Emblem Engage
After unlocking the main story mission for Chapter 15 (!Dancer in the Ruins) you’ll unlock Byleth’s Paralogue, The Instructor, which can be found to the east of Shadowy Moor located to the east of the world map. As this is one of the tougher Paralogues when you first unlock it and has a suggested level of Advanced Class Lvl 5, you may wish to wait until you get a bit stronger and acquire some more Emblems.
How to Defeat Byleth at the Sacred Tomb
The main task in the Sacred Tomb, beyond defeating Byleth, is to ensure that the other enemies don’t smash the pink crystals or you’ll get no additional reward for completing the battle That reward comes in the form of a Talisman and an Elixir so long as you end the battle with the majority of crystals still standing (we had two crystals smashed and got the reward).
Still, this means that Byleth’s forces will be focused on that task and will only look to head for and attack them during the Enemy phase. Byleth himself can be found surrounded at the far south of the map, which you access by heading up the stairs on the west or east. With that in mind, you should split your squad between the west and east side, with a unit or two dealing with the dragon fabrications in the center (Alear is a good choice for this).
Units that can fly are a good choice for this battle, such as Chloé, Ivy, and Hortensia. Take your forces up both sides while dealing with the enemies, a lot of them are Armored so you’ll want magic users (or Levin Swords/Radiant Bows/Hurricane Axes) to penalize their low Res.
Once you reach Byleth, the Martial Masters nearby will warp the other nearby units to the ground below to try and divert your attention. If you want the bonus reward, be sure to leave some units in the center to deal with this threat appropriately. Byleth himself will also close the distance after using Goddess Dance to buff his nearby allies.
Byleth comes with two Revival Stones, so you’re unlikely to take him out in a single turn, and you’ll want to focus on melee over magic due to his natural high Res. He’ll also respond to ranged attacks if he’s using the Sword of the Creator, so be wary of it when trying to attack him from distance with a magic-user. He will alternate between his other weapons as the turns go on, so look to defeat him within two combat turns.
Be sure that you take out the Martial Masters before you focus on Byleth, as they will heal him and draw the battle out longer. The best method for dealing with Byleth is to hit him with the Killer weapons, to hopefully preempt a Critical hit and give him less options to counter. Once you finally defeat Byleth, you’ll complete the Paralogue and unlock Byleth’s Bond Level cap.
All Treasure in the Sacred Tomb
There are no chests to track down and loot in this battle, so all of the items will come from enemy drops. All of the enemies with drops available will all drop Gold in the value of 1000 G. On top of that, you’ll also obtain a Talisman and Elixir if you should defeat him before too many crystals are smashed.
