[RPG] Does Mind Blast work through barriers (e.g. walls)


I'm specifically looking at the Elder Brain's Mind Blast. Based on the line of effect rules for spells, I would say no… But it's not a spell really. Based on logic, I would say yes, because psychic attacks wouldn't be affected by physical barriers (unless we're assuming it's creating a physical force with its mind). Any thoughts?

It works through barriers

The Elder Brain's Mind Blast (Volo's, 174) states:

The elder brain magically emits psychic energy. Creatures of the elder brain’s choice within 60 feet of it...

This is simply an ability that the Elder Brain has and the language has no limitations about creatures they can see, etc. Without those limitations, the language can be read normally that any creature in range that the Brain is aware of is at risk of this ability.

It dovetails nicely with their Creature Sense ability:

The elder brain is aware of the presence of creatures within 5 miles of it that have an Intelligence score of 4 or higher. It knows the distance and direction to each creature, as well as each one’s Intelligence score, but can’t sense anything else about it.

They can first determine there is a creature, and then once it's in range they can hit it with a Mind Blast.
