Periclase:

Weapon:Perhaps a hammer and nail to symbolize “breaking around” an object where a nail is driven into an object to crack it open (hammer can be used separately when needed)“Named by Arcangelo Scacchi in 1841 from the Greek περικλάω, to break around, in allusion to the cleavage.”https://www.mindat.org/min-3161.html

Ability:Has magnetic abilities and properties“Thus these stones, called Stones from Magnesia in antiquity, with their unusual magnetic properties were the reason the terms magnet and magnetism were coined.”https://en.wikipedia.org/wiki/Periclase
