Uh, yeah. Substitute "Astral" for "Sorcery" in my above post....
(Man, was I asleep when I wrote that?)
I know about the Mind Duel vulnerability, but I'm not really worried about it. Late-Age TC aren't the kings of Astral magic, really. As long as I keep Team Tarrasque away from their pretender (who
is a high-powered Astral mage, but fortunately immobile), I'm not too worried.
Oh, and did I mention that I'm playing against the AI?
To be clear: I'm not pretending that Team Tarrasque is an efficient or optimized strategy. But frankly, I think that any strategy involving GoR'ed & empowered Tarrasques is likely to be an exercise in overkill anyway. I mean, if you have that much gem income to spare, haven't you already won the game?
