Key ability
Brace
Benefit 1
When using the Prepare action to prepare a melee attack with a polearm, if your target of that prepared attack moved more than 20ft that turn (excluding teleports), your attack gains Full Pierce and does maximum damage. Against a mounted enemy this also gains Sure Hit and on damage, their movement becomes 0 until the start of your turn.
Benefit 2
On mastering this class, the Sure Hit property (but not the movement nullification) of your prepared attack against mounted enemies now also applies against Beast type enemies that are large size or bigger.
