Easy way to beat Imhotep : Use the new sword you got after beating Anubis, Cut the chains on the death bed to free Evy. Imhotep will talk trash to you after , so just kill the jabroni by throwing Amulets at his flying ghost mummies. There are at least 5 sets of them .Once you do that, Johnathan and Evy read the book of Amun-Ra and Imhotep turns mortal . Kill him any way you feel like it ! This jabroni is the hardest enemy you'll ever face! It took me a while to figure it
and I hope this helps you !
