In The 2nd Runner, Jehuty re-acquires a few of the subweapons lost from before Leo Stenbuck hid Jehuty away on Callisto. Though many subweapons make a return, five new subweapons can be obtained to add to your arsenal.
Mummy is not a weapon, rather, a shield system. It takes appearance of the Mummyhead shield, but it is much stronger. The shield can defend against virtually anything thrown at Jehuty, including previously unblockable attacks, provided the subgauge has sufficient amount of subenergy. However, the shield is not effective against HALBERD, which can penetrate the shield easily. Holding the O firmly will repair damage Jehuty has taken.
