Sticking Potions

If there was a sticking potion, it may be whatever potion you choose (Slow falling, etc.) but brewed with honey. It would be similar to a splash potion. You would splash it on a mob, but any mob that gets close to the mob with the effect will get the effect, as long as it's still active. This would be good if you only have one potion, but need to infect the whole crowd of mobs. The mob that got the effect might have a stronger effect than the others. The others would be able to spread an even weaker effect, those a weaker effect, and so on. PROS: You could use less potions on bigger crowds of mobs. CONS: Better run, because the effect works on you too, so if you don't want the effect, better get out of the way.
