Heh, figured I'd come up with something that'd break the system. FWIW, I believe that it makes sense to just include equal functionality across all realms -- that is, if downto() works for skills, it might as well work for advantages, attributes, etc. Since GURPS is so universal,
something weird is always going to come up. :)

I can add it for the future. For now, you might be able to cheat by simply using control_downto() directly. I don't think it'll be deleted if it's there outside of the context of a template.

Ha! GCA has been fooled -- yes, control_downto(4) works!

However, if the version of Divine Favor using it is used inside a template, odd things may happen.

Double ha! Mad science!

Anyway, I'll see about adding downto() support directly, and see about getting an update out soon. Been trying to get a new codebase working, but another update with the current setup will have to happen sooner than that, I think.

Thanks, Armin!

I hadn't thought of the needs(), but my backup plan was going to be to recost levels 1-4 as all being 15 points (so 15/15/15/15/20/25/etc.) and then using init(4). That wouldn't
prevent a user from going down the chain, but it'd at least make it less likely. As long as this control_downto() doesn't break anything, though, I prefer it.
(And yes, I'm off to test what happens when I stick it in a template with some #codes . . .)
