Wizards shouldn’t have a Skilled skill cap in polearms; they’re not supposed to be great with martial weapons like that.

Reaching Skilled in polearms allows you to use them in melee with no penalty.

New artifact Fishing Pole, some sort of polearm that deals double damage to all sea monsters and can hit squares as if you were Expert (in the full 2-square-wide ring around you), regardless of your polearm skill.

Since polearms are designed for use against mounted enemies, they get bonuses versus all u and C monsters. Also mounted enemies, if in a variant that has monster riding.

While wielding a polearm, moving orthogonally towards an enemy that is 3 spaces away (making it 2 spaces away, after the move) makes a free attack on that monster.

While wielding a polearm and attempting to move in a direction where there is a monster 2 spaces away (and no monster 1 space away), attack with the polearm instead of moving. Also attempt an attack for monsters 2 spaces away diagonally if polearms are Expert. To hit a monster a knight’s move away, it still has to be applied. If preceded by the m key prefix, move into the space normally and don’t try to attack.
