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

[Iron]

Maybe Forthright could use Weather Ball to dislodge some dust from a particularly dusty nook/high up Furret tube that's less likely to have been well dusted?  A cloud impacting a spot like that and then dissipating would be bound to spread some dust around.  Just need enough to start the Sandstorm, and there's always at least a little dust in the air to help contribute to that.

That would work. It's not too different than the Scimitars using an attack to chop up some metal and produce a sandstorm of their own.

Something like a Hippopotas or a Legendary could probably summon a sandstorm indoors without any setup.

As for Windos' thoughts, I have no problem with the interpretation that a Pokemon would be strong enough to summon weather indoors, it's just not how I've been interpreting it and it's too late to change it without good reason. Sunny Day is the weather that makes least sense indoors, so it does seem sort of fair to keep all the weathers on a level playing field. 
The rulebook explicitly says you can't summon Sunny Day indoors. I do like the creativity this rule has brought out, starting with Shiva's ice mirrors in Zamboni's Gym.

Anyway, that's the rule for this campaign, maybe we will see a different interpretation in the next one.
