You're thinking too small. Let me tell you, admitting I am a sadist and a dom, who'd love to be in the skin of that blue beauty, what you'd really want to trap is a sorcerer specialized in buffing. 10% here or 15% there isn't too much in a normal setting, but with a big enough baseline... Well, let's say the difference may be between seeing "only" a tower crumble before a single solid strike — and facing devastation of half your castle.
I'm sure I could lure in some young, ambitious magician to act as a kind of living amulet, pulled in by honeyed words describing the impact they could make partnering with me. Would be a safe environment for them to get some experience in, too, wouldn't you say? Frankly, they'd be getting the better half of the bargain, right? Hah.
The IS a Japanese idiom which fits well here: "Like giving an Oni a kanabo", i.e. handing an advantage to the already empowered. Why should they waste their skills on anyone lesser?
