Godstones are items that imbue weapons with secondary effects. Such effects may include bonus damage (generally good for PvE) or inflict a special status on an enemy such as stun or paralyze among others (preferred in PvP). Godstone effects are applied by chance, with every skill the player uses granting a small probability of triggering the godstone effect. The activation rate % varies per godstone.
About Godstones Edit
As of 4.7, players can just right-click the godstone they wish to socket and then click on the target weapon which will receive it. Alternatively players can select the weapon they wish to imbue with a godstone and then socket it via the Godstone Socketing tab in the gear modification window. Once applied, the weapon will glow with its newly added power.
Only one godstone can be used per weapon. When you apply a stone to an item that already has a godstone socketed, there will be a warning stating all previous stones will be destroyed.
Illusion Godstones Edit
Instead of using regular godstones players may also opt to use an illusion godstone. Illusion godstones provide better activation rates and effects compared to their regular counterparts, but have a small chance to be destroyed each time the effect is triggered. If this happens the player will receive a notification that the godstone has broken and will disappear within the next 10 minutes. Although illusion godstones can break in theory, there have only been a handful of cases where this actually happened. Regardless, to be completely safe, players are advised to use regular godstones for the rarest and most valuable effects (e.g. the highest damage godstones or the ones that inflict paralyze) where possible.
Acquiring Godstones Edit
Godstones (or rather the pouches containing them) are relatively common rewards from events. Illusion Godstones can be acquired from the Atreian Passport or by completing dailies for the Fortuneers (Elyos, Cygnea) or Charlirunerk's Daemons (Asmodians, Enshar) factions and trading in the awarded tokens for an illusion godstone pouch. Godstones can also drop from monsters in instances at an abysmally low chance.
