Players would love to have a bugspray for these nasty creatures especially if they're new and don't have a bed yet to drive them away.  Maybe leave 1 or 2 bugsprays for new users who join and get the Wanderer rank.

This would help increase moral especially with newcomers.  Also, maybe a lil less raging from other players too haha.

On a scale of 1-10, since it's a potion that has to be made and coded.  Possibly 2-5/10 (1 being easiest and 10 being hardest)

What do you have in mind for this potion? How would it repel phantoms?

i see 3 options
1) despawns phantoms within range of player. Makes it valuable in groups
2) prevents phantoms from spawning, basically a bed in a bottle. 
3) scares phantoms away. A drinkable cat effect. 

Were you thinking of something like one of these or was there something you had in mind?
