Pokémon Mystery Dungeon: Blue Rescue Team Tips

Projectiles = Poké
If you've been playing for a while, you probably have a ton of gravelrock in your inventory. Way more gravelrock than you'll ever use. Gravelrock sells for 5 poké for every 1 gravelrock. That doesn't sound like a lot, but if you have hundreds of gravelrock like I do (and I'm fairly certain a lot of you do as well) it adds up to thousands. This is the same for other projectiles (Iron Thorns, Silver Sticks, Geo Pebbles, Sticks, etc.)
