I was also contemplating empowering in Astral magic, for the transportation, Luck, Etherealness, and Astral Shield. Astral Shield seems like a particularly good choice for a Tarrasque given the poison aura. (Normally you'd rather have e.g. Fire Shield so that chaff units kill themselves on your fire shield, and paralyzing the chaff just slows that process down.) I'm rolling in pearls anyway in my current endgame, so empowering to S2 and then using a Crystal Coin and Ring of Sorcery should let me Gateway to the front lines; then I'll probably stick with a Ring of Sorcery and an Amulet of Resilience.

As you said, not efficient at all, but perhaps tremendously fun.
