[quote=@Sionnie] well then how does Rift work? i mean to exact specification.. like uses per day or level requirment and even casting materials.. i hope that even i could use it as a Warlock later... as it has great utility for a rogue.. [/quote] No such spell as Rift. If there was I would imagine it would be a 7th level spell that could be instantly cast using a material from another plane. You would open a rip in reality and travel to the origin of that material. A bad spell to be honest. Theres already planeshift for that...
