Chapter 15 (Golden Deers) - Enemies

Enemy Stats

Loot

There are three possible dropped loot items in this stage, found with the Fortress Knight, Sniper, and Ashe in the center of the map.

Concoction

Heals 20 HP. Good to have for your high mobility units that tend to flank away from your main force with your healer.

Chest Key

Unlocks chests.

Killer Bow

A bow with a high crit rate. Great to keep on Claude or any of your other archers.

Chapter 15 (Golden Deers) - Chests

There is only 1 chest key held by an enemy. See the loot map above.

You can purchase a chest key before battle, or if you have keys in the convoy, access them from Byleth.

If you have a Thief, of Assassin in your party, you can have them open up one of the chests using the Locktouch Ability.

Silver Shield

Offers +4 Prt for +4 Wt. Slows down units, so maybe only worth getting to toughen up healers, or if you already have Fortress Knights.

Bolt Axe

A magic axe that uses its user's Mag instead of Mt and targets Res instead of Def. Useful as a ranged weapon for axe users with good Mag who need ranged weapons, but a bit redundant because Mag works best against armored units, which axes already do well against.

Chapter 15 (Golden Deers) - Map Features

Surrounded by lava and craters, fliers dominate this map. Take enemies out one by one before rushing in.

Terrain Types

Reinforcements

When you get close to Gwendal, Judith and her troops will arrive as ally units. She will appear on the northeast part of the map.

Chapter 15 (Golden Deers) - Tips and Tricks

Take Out Long-Range Units With Fliers

With fliers' high movement range, you can take out enemies one by one before retreating back to a safe position with the extra turn. Be careful of their range as the archers and snipers may focus all their attacks on you if you are in the wrong position.

Do Not Stay Long On Craters

Craters reduce a unit's HP by 20%, and this would be bad for weaker units with low HP if they get ganked. Be patient and units like fliers take out enemies past the crater before you rush in.

Focus on Defeating the Commander

Gwendal is found on the lower-right side of the map and can be defeated in a few turns. There is no need to eliminate all the enemies, unless you are grinding for Exp.
