Could you please modify the maximum value of SPELL_DAMAGE_BONUS = registerAttribute("ars_nouveau.perk.spell_damage", (id) -> new RangedAttribute(id, 0.0D, 0.0D, 10.0D).setSyncable(true), "50b50137-9c92-4e64-b350-6044e9e609de"); to 100 or greater? In RpgSkillable, spell power can be enhanced based on skill levels, but clearly, the current value of 10 is a bit small.

Good catch, fixed next update.
