[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Dragonstrike]

There's only one restriction I see on Telekinesis being able to lift things according to Bulbapedia's page: that that the target's not rooted to the ground (like Diglett and company) or been forced to be grounded in some way (like holding an Iron Ball or under the effects of Smack Down, Ingrain, Gravity is in effect, etc.).  Telekinesis fails/is cancelled out if that is a factor.

The book doesn't mention any restrictions either (though I think Bulbapedia's listed ones are reasonable).  Sky Drop is the only move in both the games and book that fails if a target is too heavy for the user to lift (200 kg in the games, consult the Strength threshold chart in the book), I believe.  I think the difference there is lifting with physical might instead of psychic power, as Telekinesis is a rather powerful move.
