Coldstorm Cleric is a build that makes use of a Flail, such as a Chainlink Flail, and its high damage and Strength scaling. This is paired with the Stormcaller Ash of War to increase Bloodloss build-up, maximizing damage output and the chance to stagger opponents. This build does heavy damage to targets, but it also builds up Frostbite once you add the cold infusion, and blood loss maximizing your damage output.

This build is also paired with the Fire's Deadly Sin Incantation, to continuously retrigger the Frostbite Status Effect since it is a continuous source of fire damage it can reliably reset the Frostbite status effect on enemies for build that inflicts frostbite rapidly.

This build explores the following talismans, the Warrior Jar Shard or Shard of Alexander to increase Stormcaller damage, other Talismans you can consider have also been added to the list,

Overall, this build utilizes each equipment piece to increase damage output enhance to reusability of the Stormcaller skill, and continuously cause a Status Effect build-up on opponents to further maximize their damage intake. Other equipment pieces you can carry should typically increase the damage of your build. When finally implementing this build, wait for an opening before finally mashing L2 to trigger the Stormcaller skill, getting in a number of hits that would build Frostbite, Hemorrhage, and build your attack power which could work all together to stagger your opponent and give you a chance to continuously repeat the process and melt away opponent HP.
