fe3h umbral steel.jpg

Umbral Steel

The chest is in the same location as the previous eagle vs lion battle. There is no obtainable key in the battle however, so brining a unit with lockpick or bringing a key is a must to open the said chest.

Chapter 17 (Blue Lions) - Map Features

At the center of the three armies, there is a hill. There are three Heal Tile+'s on the map, one for each of the other house leaders, and directly south of the pyramid. At the very top of the hill lies a ballista, manned by an opponent, that can be used by units that are skilled in Bows.

Tiles Description
Wasteland Difficult for cavalry to traverse
River Navigable only by fliers
Forest 1 Prt, +30% Avo, except for fliers
Cliff Navigable only by fliers
Fence Navigable only by fliers
Pillar Cannot be crossed
Stairs Difficult for cavalry to traverse
Heal Tile+ 1 Prt, 1 Res, +30% HP each turn for non-fliers
Ballista 5 Mt, 15 Durability, 3-12 Rng, Requires Bow Skill of D or higher
Fiery Floor -15% HP each turn for non-fliers

Chapter 17 (Blue Lions) - Tips and Tricks

Armored Knights on the Hill

Fortress knights
Most of the units guarding the hill are armored knights. Make sure to have your magic users ready to engage them.

Claude's Cunning Ambush

A few turns in, Alliance forces will pop up from behind your troops and the forest they are stationed at. Leading the ambush from behind is Hilda, so be careful and keep a good rearguard. Leonie will also join the fray.

The Burning Pyramid

If there are Kingdom and/or Alliance units on the center hill and no Imperial forces there, Edelgard witll set fire to it, causing 15% HP damage to everyone standing there per turn. Once you clear the ballista, evacuate it at once, or if possible, send a minimal force.

Petra at the Ballista

If you manage to defeat Bernadetta from afar, but go around the hill, Petra will go from her position at the south of the pyramid and take the ballista if the hill is clear.
