Terraria (Wiki): Palladium Pike

The Palladium Pike is an Ore Spear that pierces enemies and an alternative ore counterpart for the Cobalt Naginata.

The Palladium Pike has a blade that resembles an axe but cannot cut trees. It looks more like a halberd than a pike, and the Orichalcum Halberd looks more like a pike than a halberd in terms of appearance. 

A Palladium Pike cannot autoswing. Its attack reaches 11 tiles in radius. At an optimal distance, the Palladium Pike can pierce five enemies. However, multiple bodies will be damaged should they all line up for the player.

When normally used, the Palladium Pike will not emit light, and attacks do not go through walls. It has slightly increased knockback and has the same base damage as Cobalt Naginata. It is also the second slowest use time among Ore Spears.

Combat-wise, all Flask items will imbue their unique effects since the Palladium Pike is a melee weapon.

The Palladium Pike is best modified with Godly or Demonic for overall stats improvement. Both modifiers equally increase the average damage output.
