Mechanical Marvel is a unique Weapon in Pillars of Eternity 2.


For many years the innovation of the traditional arbalest was thought to have stagnated. All of that changed the day two wagons collided – one driven by an animancer carting a heavy load of copper springs, the other by an enterprising arbalest enthusiast. Revelation struck as the dust settled and the fated travelers worked to disentangle their spilled cargo.


From that day forward, the pair became inseparable business partners – marketing their spring-loaded improvement on the arbalest to weapons dealers across the Vailian Republics. Others have gone on to copy their design, but this device is thought to be the original prototype that spearheaded great changes in weapon craft and an even greater friendship.

Mechanical Marvel Unique Enchantment Upgrades

Enchantments play a vital role in a player's equipment, these Enchantments provide different special effects that can be used as an advantage in battle. Some Unique Weapons carry multiple Enchantments that players may equip and some Unique Weapons only has one Enchantment. These Enchantments can only be found in Unique Items and can be upgraded if needed.

Players can unlock all of the upgrades listed for a Unique Weapon's Enchantment, however, some upgrades replace the current enchantment, and some can be stacked as bonus effects. By doing this, players must have the required ingredients and sufficient Copper Pands (CP) to be able to craft their preferred upgrade.
