Converting monsters from Tales From The Infinite Staircase

That looks good, and I'm happy to include a sample Master Slaiyith. I mostly just don't think we need a specific new monster or template.

Let's do the additional spells. How about these?
0 - message
2 - touch of idiocy (don't use this one much)
3 - suggestion
4 - lesser geas and perhaps polymorph

I'd prefer charm monster and either enervation, resilient sphere or black tentacles for the 4th-level spells.

The lower level additionals work for me.


Extradimensional Explorer
Let's go with charm monster and black tentacles at 4th level, then.
5th - dismissal, mind fog, telekinesis, waves of fatigue ??


Extradimensional Explorer
Sure, that will all be fine.
6th -- antimagic field, control water, freezing sphere ??
I'd like to keep control water since it feels right thematically, but I'm not too fussed about the other two.
