Shapeshifting abuses

[hcobb]

Just a quick poll to see how far you allow Shapeshifting in your TFT games.

First: Can you retain full IQ when shapeshifting into another form with either listed or max IQ much lower than current IQ?

Can you retain talent and spell use when shapeshifting into another form that isn't a spellcaster?

Can you shapeshift into ...

The form of a known living person (especially given the note at ITL 44)

If that person is younger or order than the spell subject does the spell subject then age in line with the target age?

A wraith, retaining all other attributes for an indefinite no-cost to maintain insubstantiality?

A vampire, gaining +4 ST and regeneration?

An elemental, and if so do you get the immunity to illusions?

A wight, for immunity to normal weapons?

A demon (from what base ST?!?) gaining controlled global teleportation?

A gate spider so you can spin your own gates?

A 1-hex dragon? (If so how many years does it take to grow into a 2-hex dragon?)

A Basilisk?
