Bardic Ignorance (5e Feat)
From D&D Wiki
Prerequisites: being no bard
Throughout your burdensome journey with a bard, you have learned that these scallywags are no real threat to anyone thats wields REAL magic. You can just laugh off any of there pitiful attempts to interrupt REAL spells.
You can ignore all counterspell attempts or the Cuttings Words feature used against you. They must either have Bard levels or use the Bard spell list in some way.
