Maybe it should Jandk, but as Gm4him said, it doesn't have to since these tadpoles are not normal. He understood your point, no point in pulling teeth and trying to imply he and others can't understand basic concepts.
Edit: Would you find it more acceptable if the roll was called Netherese instead?
1. I'm not sure he did. Nor am I sure how you would know. I'm also not convinced that unsolicited advice was helpful.
2. Calling it Netherese would... call into question a lot of things. If the powers are the result of the Netherese magic holding the tadpole in stasis and not stemming from the tadpole itself, it makes me wonder why the tadpole is necessary in the first place. But that aside, as it's not called Netherese, and rather it *is* called [Illithid], I think the point stands that it should probably be an Int roll instead.
