The Memorium was a scythe forged by Martha with the help of Ianite using her mother's (Kikoku's) techniques. The Memorium was gifted to Jordan to persuade him onto Martha's side. The scythe was forged out of two obsidian tough tool rods, one obsidian tough binding and one obsidian scythe head with the modifiers of quartz, a ball of moss and a piston. The scythe had 25 total modifiers, which required 22 extra creative modifiers.
Martha later upgraded the Memorium to have Knockback and Beheading X. This changed the look of the Memorium to have a purple cover with a green eye of ender in the corner and totalled the extra modifiers up to 36.
Memorium is the main melee weapon used by Jordan.
