So, your mage is big and bad, and has a big, bad Talisman, full of juicy effect. What effects went into it? Some magi would have uniquely personal effects, but I wonder if there aren't some that are more or less universal - or if not a specific effect, then a certain "class" of effect.
With a generic mage with Magic Theory 8, let's say it was opened for ~16, so maybe no more than 160 levels of effects, give or take. (Yes, more is easy for some, but some are eager to get started!)
Ones that jump to mind are:
o Leap of Homecoming (or something lesser, a "Marines, I am leaving!" effect that ignores casting penalties and botch chances (well, there's still Finesse, but still...)
o High Penetration Attack (or perhaps a small variety of them - Physical attack, vs Spirits, DEO, depending on custom and concerns.)
o Wards against X, Y, Z, (and as much of the rest of the alphabet as possible).
o High Penetration Intellego (What the hell is that?!)
o Other "Save my bacon" effects, of any variety.
