Choosing a profession

When to choose Iron Wall

Automatic shield for the lowest-HP ally

At the end of each turn, Iron Wall shields the other ally with the lowest HP. An enemy attack against a shield the wearer granted also gives the wearer Armor.

Best fit

Teams with a fragile carry who needs a new shield each turn and a tank who can take the attacks that follow.

What you need

Use this where enemies actually hit shielded allies. That keeps the wearer’s Armor buildup going.

Where it struggles

If enemies only hit the tank or the main threat is one lethal hit, a damage-sharing route may serve the team better.

Before you advance

Are enemies targeting the ally with the lowest HP?
Can the shield absorb the usual incoming damage?
Would Lionheart keep that ally alive more reliably?
