I doubt anyone would play one if every time they cast a spell, there was a chance of a magick-themed mul-rage episode.
Be a victim of that unfortunate dice roll? Absolutely not.
The OP here made an analogy to mul rage, someone rightfully replied that that is a mechanic you need to find out about IC, so we shouldn't even be talking about this at all.
But can I just say this whole situation, including the assertion that we can't talk about existing rage code, is ludicrous and I 100% agree with Lizzie's summation?
To avoid getting in trouble by talking about things we shouldn't be talking about, let's just do a thought experiment here.
Imagine playing a game of D&D, and suddenly your DM says "Oh sorry, you critically failed a dice roll I just made behind my DM screen here. Your head explodes! You are now dead." You, as a player, would likely say "WTF?!?!" The DM would then say, "Oh, when you picked the super-psionicist class, what you didn't know is every in game day I am rolling two d10s and if you get two zeros your head explodes and you die." You, as a player, would likely say, "Well why didn't you tell me that's how it worked to begin with?! I thought as a super-psionicist my head would maybe only explode after a lot of exertion or getting injured." The DM then shrugs and says, "Ooops, sorry, it was just a random dice roll all along. Death is permanent, maybe pick a different class next time, now you know how it works."
That is the
exact situation players of certain in game races are in now. Before even remotely considering extending this mechanic to gickers, we need to fix the situation for our existing guilds/races. It needs to be spelled out extremely explicitly, both what causes the episodes and what prevents it. Gickers are given the exact spheres/etc for casting spells, and any "rage" code should be made just as explicit. Once we fix the situation and do that, I
might be in favor of something like this.
