Q 110: Is there any rules reason to keep me from storing hunderds of cantrips in a single ring of spell storing?
I assume they count as 1/2 a spell level like they do for everything else.
sadly, it seems that the telepathic static "negates the telepathy of creatures within 20ft" instead of making a 20ft radius deadzone. yeah, it stops mindsight, but only when you get within 20 ft of them.
Is also a grammatically correct reading. The 'of creatures' denotes the source of the telepathy.
And the interpretation is supported by the Divination blocking, as snakeman said.
But it's really unclear. I would rule on my reading of it if only to have
some passive counter to Mindsight.
