kay! sooo,go to IF, obviously...
go to this duel spot under the stairs in the corner and duel w/who ever you want to polymorph/fear into old IF........(asuming ur a mage/lock, if not then reverse what i jsut said)
afterwards, as your dueling, run here, jump on fire and jump on window sill.....have mage buddy stay down, do this as fast as posible bcas ur exiting dueling area in 10 seconds...but you need about 3 seconds to polymorph, should be easy if your not a total retard.....................anyways SS below.......
now stand here on the window sill and have ur lock/mage friend sheep/fear you, and POP....you go trhough window and end up in old IF
and thats the way to get into old IF
