I am out of ideas - remove mods one by one or in groups until you find the mod causing this issue
Or use a pre-configured modpack as working base and add some mods
Iceberg is twice available
Maybe make a test with adding a font texture pack and enable it
https://www.curseforge.com/minecraft/search?class=texture-packs&page=1&pageSize=20&search=font&sortType=1
So try other builds of Epic Fight Battle Styles
Or install a modpack which is using these mods and check for the used builds there

WeaponsOfMiracles is not working with the current epicfight build
Try other builds of epicfight and/or WeaponsOfMiracles until you find a working combination
