DnDBeyond recently released a League of Legends themed adventure that introduces new unofficial subclasses that, while certainly interesting, pose some serious balance ramifications.
One of the biggest offending abilities allows a PC’s weapon attacks to ignore resistances and immunities for any damage inflicted by the weapon attack. I can’t think of single feature or item that grants this effect.
Are there any features or magic items that allow weapon attacks to ignore damage immunity against the weapon’s damage type?
This effect can be permanent or transient.
