Working with Dangerous Power

The one thing that I have always felt lackluster about most Adventure Games that I've played is how the magic systems work. The requirements to cast spells felt a little video game-y and there wasn't really a lot of risk to harnessing and manipulating what seemed to be strange and wonderous power. You fail the roll, you might hit an ally instead and lose the spell for the day. That's kinda it.
Dungeon Crawl Classics handles their magic is a very interesting and scary way. If you are a wizard, you are going to inevitably end up kinda fucked up the more you use your abilities. Mercurial Magic aspects combined with vicious corruption tables after failure make for a very haunting combination.
The only issue I have with using DCC is that the whole thing is so damn big and overwhelming in both scope and sheer amount of table searching so I've been looking elsewhere for an alternative that can satisfy my desire for weird fantasy with a brutal magic system. The conclusion that I came to is that Old School Essentials (OSE) would be a great choice as it is lightweight, deadly, and easy to learn so why not just bolt on the corruption table to that? And that is exactly what I did. Many of the below entries are from DCC's core book with minor changes or omissions to make it fit OSE better but it can easily be used for any OSR system out there.
Before I drop the table, a few clarifications. The list is 26 entries long. I've made Minor, Major, and Greater Corruptions into a range of results as opposed to individual tables and laid all of the entries into one, easy to reference table. The breakdown is simple, spells of level 1-3 would be considered Minor, 4-6+ would be considered Major/Greater (Referred to as Major from this point on) for easy of porting.
The process is quick and simple. If your Magic User critically fails their roll, depending on the level of their spell, you have them roll either a d10 or a d20. Spells of level 1-3 are open to Minor Corruptions and are a d10 is rolled on the table. Spells level 4+ are open to Major Corruption and therefore are rolled with a d20. The level of the spell is then ADDED to the result of the roll and the table is referenced. This helps gate lower level spells from getting really bad results and also allows higher level casters the chance to get lucky and get a possibly less shitty outcome for their hubris.

Example: Mork the Wizard attempts to cast Magic Missile and rolls a 1. Since Magic Missile is a level 1 spell, Mork will roll a d10 and add the spell level. He rolls a 6, so his entry would be 7 after adding the spell level (+1). The result is that one of his legs has now grown 1d6" and he walks with a strange gait from now on. Simple!



Corruption Table:
When a spell casting roll critically fails, roll on the table below.
Minor Corruption (1d10+Spell Level): Level 1-3 Spells
Major Corruption (1d20+Spell Level): Level 4-6+ Spells
