Thank you for taking the time to consider my mod! I have a Ko-fi, but please understand my content will always be free. Your consideration is greatly appreciated! Ko-Fi Link. Here you can sometimes see samplers of things I am working on as well as a free 2014 5e class in my shop.

SUGGESTIONS:
Gear mods by GraphicFade are perfect fits for this class.
Another Gish in a similar style, The Spellsword, who gets a special shoutout for changing his mods name because of mine even though his was first. I promise to do research before accidentally stealing another name.
Everybody Moves Fast has a good sweet spot for faster movement without breaking your characters neck.
The AI isn't the greatest. Nightmare Difficulty helps.
Doing 300-900 damage in a single turn? Tactician Enhanced can boost stats. I always crank enemy HP up to 400%.
