What class combo is your character, anyway ? You show her in medium armor, light armor, and yet from the combat log she's clearly at least part Storm Sorcerer.
Maybe Tempest Cleric with Storm Sorcerer ?!
P.s.: Found it on the net, for example here:
https://www.youtube.com/watch?v=g4fpAhtm5xo For those who dont like to watch videos:
Basically start as Storm Sorcerer (for CON Saves, so concentration stays best), get 2 levels of Tempest Cleric, get 1 level of Wizard (this class taken last, so scrolls and items use INT), then the rest all Sorcerer levels, for as many Sorcery points as possible.
Pump INT like crazy (start at 16 and get it to 20) and use Sorcerer and Cleric spells only for support stuff without saves or attack rolls.
You can then use lightning spells for crazy peak damage. Quickened Create Water to make opponents wet to double damage, then upcast the usually poor spell Witch Bolt, then use Tempest Cleric to assert maximum spell damage (Thus 6d12 for a level 6 Witch Bolt turns into 72 damage), and if you can also make sure theres a critical hit (for example if you stun the opponent) thats again double damage, and of course you can also twin the spell to deal this damage on two opponents, and you can hasten your character to get two such spells out in a single round, or you could back then when that video was made, I think they did something to haste ?
Drawback is this character spends both feats on +2 Intelligence, so there is no fun with any extra functionality, or even just the basics like War Caster.
You will also only have 6 wizard spells readied at any point, from 1 level of Wizard and Int 20.
Also opponents who are immune to lightning damage will completely nulify this build, and battles with lots of opponents wont be going too great either, though the later is pretty normal for spellcasters.
