I'm pretty sure it's just an oversight. Instead of doing something like this:

Gems Spent - (Cost x (1 - bonus))= extra gems (assuming bonus is a percentage multiplier like .20)

they went with the simpler version of:

Gems Spent - Cost = extra gems

Of course this oversight has been around since... pretty much forever, so they just kinda kept it around as one of those hidden rules to make new players crazy. A throw back to the old days perhaps? Who knows... It's just that everyone who's been around for a while knows about it, and frankly it's not really that bad IMO, so there's really no outcry for it to change anytime soon.


FYI: your extra gems is compared with their extra gems, and the one that used more wins the global slot (or kills it in the case of Dispel). Or in the case of domes, the extra gems = the duration of the spells. The ritual bonus doesn't do anything in these cases unless you're just casting them at the base with no extra gems (for various situations).

Oh, and I'm pretty sure Fates of Oedipus always destroys the Eye... (I don't think it even has an extra gem box). Of course that could just be me not getting enough sleep.
