How Is a Sorcery Spell's Skill Percentage Determined?

[Deepest_Lore]

Started digging into the RQ:G rulebook a few months ago and I have a question about sorcery spells. To cast a sorcery spell the caster must master the spell's corresponding Rune(s) and Technique(s). I understand how one masters those but how is the spell % determined to roll against when casting? 

Example:

(Insert spell name) 75%

So the caster would roll 1d100 and get equal to or under 75 to cast the spell plus any manipulations and over come the targets POW or resistance if needed.

But what is determining the spells 75% of being cast? I'd assume it's the sum of the degree of mastery of the spells required Rune(s)+Technique(s). But that is just a guess since the chapter doesn't clearly list how Technique %s are derived if so. I hope this made sense. Feel free to correct me if I got anything wrong at all.

RQG page 386: 

Each sorcery spell is a skill, and a sorcerer has a percentage chance to successfully cast it. Sorcery spells are modified by the sorcerer’s Magic skills category modifier, as well.

It's a single roll (don't forget to add any sympathetic magic modifiers and ritual bonuses). As with all magic, there may be a second POW vs POW roll needed.

A Sorcery spell's level is determined by cult and occupation when creating your adventurer (plus any experience, training or research) eg:

A philosopher (RQG 70): gets three spells starting at 00% then adds 

Occupational Skills: (Sorcery spell) +10%, (Sorcery spell) +20%, (Sorcery spell) +10%,

then if a Lhankor Mhy initiate:

Cult Sorcery: Cultists trained in sorcery start as having mastered the principles of the Truth Rune and the technique of Command (see page 381). They may add +25%, +10%, and +10% to any three spells chosen from the following list...

So you could start with three spells, one at 45%, two at 20% plus your magic bonus.

When writing down your spells, all you need to know is the magic point cost per level of manipulation

So for a Lhankor Mhy initiate who has mastered Command and Truth and knows the following spells:

• Logician 40% 2+2mp/level*
• Reveal Rune 20% 2+1mp/level**
• Solace of the Logical Mind 20%, 2+1mp/level**

* Summon not mastered so double cost to manipulate

** technique and rune mastered so normal cost to manipulate

Occupational Skills: (Sorcery spell) +10%,  (Sorcery spell) +20%,  (Sorcery spell) +10%

Was this a copy-and-paste item? I'm assuming the second should be Cult Skills rather than Occupational Skills?

Perhaps also worth noting the Learning New Spells on p.390:

Quote

At the end of the training, the sorcerer has learned the spell and has a beginning percentage in the spell of 1D6 plus their Magic skills category bonus.

Yes, but as noted, just for new spells, not the three already selected.

That's a really minor nitpick, but I don't understand why the highest skill is in the middle.

It seems like an editing oversight. It shouldn't be an issue for most people. But I see where you are coming from, since with TTRPG rules wording is very important and a minor editorial issue like that can lead some people astray.
