Sage/smudging

So, an idea I have is implementing a new piece of flora Minecraft and that is sage. When placed it looks like tall grass and as an item it looks like sugar cane. Basically, it can be crafted into a smudge stick which can be made from 3 pieces of sage and 2 string. If a smudge stick is right clicked it will start emitting smoke and the player will be given a potion effect called smudging. This effect basically makes all hostile mobs in a 15 block radius run away from the player holding the smudge stick. This effect can last for 5 minutes and 30 seconds. A smudge stick will have the same durability as flint and steel. Though if a player with the smudging effect hits a hostile mob, the effect will wear off and hostile mobs will start attacking the player again. Anyway that’s my idea, I hope you all like it! :D
