A scroll for "Explode Nihilists" spell. Any nihilist in an earshot of this spell being read blows up with a force of landmine in a fascinating fountain of giblets and blood.
A magic staff made out of Dumbledore's mop. It's not as good as actual magic staves, but still provides Level 2 (out of 6) cast-assist. It also provides perpetually active healing field.
A Grandmaster Mendeleev's Alchemy Set providing discounts for summoning rubidium, strontium, zirconium, molibdenium, and palladium elementals.[footnote]I was too lazy to use Wikipedia, instead using my chemistry encyclopedia - which is in Russian. Some of those may be misspelled as a result.[/footnote]
