Pre-EoC the Miasmic Barrage would've taken that title if it had numerous targets.

Yes, you get range xp.
You will get 48 experience for each Falador Teleport cast. You need a Magic level of 37 to cast the spell, and you can't cast the spell past level 20 in RuneScape's Wilderness or if you have been teleblocked by a player or monster. On the other hand, the Falador Teleport on the Lodestone network will grant you 0 experience, but it also free of charge.
