I think it easier than that. Once every 7 levels you can gain access to next tier magic, but if you don't have appropriate class levels, you wouldn't attain spells themselfs. That way lvl 99 warrior woud not have access to tier 10 magic. For example, a warrior of lvl 90 takes 6 levels of Druid class. He will have access to tier 6 Druid spells. But as he don't have enough mana, due to being warrior, he will fire 2-3 spells and run out of mana, and that spells would be just a basic ones, as he didn't have higher druid classes and feats that comes with them. And many such drawbacks. But in case of Shalltear, who mostly a warrior, her build perfectly supplemented by Cleric class. So there is a ways to optimise a build. Check out D&D. It may be different, but good as a reference.
