Why not invent your own recipe?

for example;

Lead Plate(R6) + Pure iron block(R6) = Scarlet Mace(R10)
may need to use a book 1 or 2 or keep trying till you get a +4 jump.

Scarlet Mace (R10) + Decicate Emerald (R10) = Bluezircon Earrings(R14)
it will also be a +4 jump so continue to try or use a book 1 or 2

you can also try using the mace with;
Red Stone (R9) + book 3 = +5 jump
Blue stone (R8) + book 3 or 4 = +6 jump
Polish Emerald (R7) + book 4 = +7 jump

let me know if any of this recipes work and i'll add them to the database. sorry i can't test them for you.
