Introduction

Hi all, this is my first guide, so sorry for any technical errors.
TL:DR; This is for a build that comes fully online in early act 2, and pushes hard into the Reverberation mechanic.
This build started as something I put together for my Tactician run to make Shadowheart, who's Trickery is definitely lack-luster. Instead, we make her Tempest, which is still nice enough thematically and also packs a big punch. Tempest Cleric applications are what will be discussed for most of this build, but there will be a section at the end discussing other options for min-max.
I'm not positive all of this works as described, some of the reverberation items are a little funky, but as of patch 4 & 5 the build feels great into early act 3, regardless of what may not be working as we want?
I hope you enjoy knocking enemies on their asses, and let me know how I can improve the guide.

Notes

Until Patch #3, Reverberation was bugged. While it applied the stacking penalties to Strength, Dexterity, and Constitution Saving Throws, it did not deal thunder damage and prone. As of Patch #3, now works as described.
The different items that can apply Reverberation do not all work as expected from their description.
