If he did not say it, he heavily implied it. Unless the Spectre is worth the whole 300g, then his math is off.

Using appropriate math (a 3-research mage of the Seraph's paths costing 140g), even using the whole 300g as a starting point gives a 16-turn turnover in RoI. And I dispute that a Spectre is worth 300g.

Another issue is one that other have brought up, in that you are not limited to a mage-per-lab with summoned mages.

Wouldn't that be funny? It can't be modded, but if only one mage could use a lab per turn... that would drastically change the nature of magic in the game.
