[RPG] Do Booming Blade and the Spell Sniper feat stack


If you have the spell sniper feat (doubles range of spells), and you use a weapon with reach, can you cast booming blade and hit a creature at 10ft?

Can you also combine this with the feats Polearm Master and War Caster to make a booming blade opportunity attack when a creature enters your reach (of 10ft)?

Best Answer

Not any more.

As of Tasha's Cauldron of Everything, booming blade now has a range of Self. This means Spell Sniper won't have any effect on it (you can't double a range of Self) and War Caster won't let you use it in place of an opportunity attack (War Caster requires the spell to target the creature).
