Strange Drugs

Each dose consumed grants one Opium Die. OD are d8’s that act as temporary MD for all spells cast in the next 10 minutes. They are always returned to your casting pool unless they roll an "8". If an OD rolls an “8” you become more addicted to the drug. One of your natural MD is replaced by a Corruption Die  (no benefit to casting but counts for doubles and triples). You can temporarily return one of your MD to normal by taking another dose of Strange Drugs. This doesn’t grant any Opium Dice unless you take a massive dose (you need one hit for every corrupted MD before you start getting OD again). Taking a massive dose is dangerous, make a Save (with -1 per dose taken), if you fail you take [doses]d8 damage. If you don’t have any normal MD left, you lose a point of Might instead.

The only way to permanently restore your MD to normal is a painful detox (each day you don’t take the drug make a Save, on a success one of your MD is restored, on a fail take d8 damage). A miraculous alchemical treatment may exist, but it's expensive and dangerous and many of the doctors who offer it are charlatans.
