When using spells like Boulder Bash, Meteor Shower and Hail Attack, some to all of the projectiles are detonated in the sky blocked by the terrain that makes up the sky area that is not avoidable or even readily apparent that the spell will be blocked, had a Boulder Bash just crash into empty space in the sky. If this is working as intended the sky area needs to be made more obvious in what will block it and what won't.
