Mjölner - Path of Exile, POE Item Price Check and POE Builds

Mjölner is a unique Gavel. When the player hits an enemy with an attack using Mjölner, one lightning spell socketed in Mjölner will be cast instantly without costing mana, similar to a trigger gem. If multiple spells are socketed, then they are cast in the order of the sockets, starting from the top left and working down through the links, sequentially. For instance, if you have Arc, Storm Call, and Spark linked from top to bottom, the Arc will always cast on the first hit, then the Storm Call on the second, then the Spark on the third, repeating the sequence with successive hits. Each gem has a 250ms cooldown once triggered, although trigger order is preserved even the cooldown has passed. In the previous example, were Arc triggered with the first hit, and the player hit again past the cooldown (ie 400ms later), Storm Call would trigger next. Multiple copies of the same spell socketed into Mjolner all go on cooldown at the same time, meaning the same spell cannot be triggered more than once every 250ms. Socketed spells are only cast on hits that are not evaded, so taking Resolute Technique is extremely helpful for non-crit builds.
