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

[PhantomUnderYourDesk]

And a little question: What instrument you are talking about? It is the Frozen Roar or something else?

Somethingelse. It's an instrument of our choice that we received in a package from Prof.Mallorn as a reward for saving the region from Deoxys Prime:

(...)Instruments (your choice) from the Ruins that reduce a Pokemon's Will by 1 for purposes of being caught, as they are calmed by the music.(...)

Here's the link towards the post.
Works without the purpose of being caught too, for example how Shiva used her flute to lure in alienmon and calm down the caged Pokemon in the lab, so if Heart-Shiva-Terra play a soothing melody on their instruments all together and ampliefied by the FrozenRoar, it might calm Huge Cocancer nicely.
