...I haven't yet learned how to take complex roots of complex numbers. 
If anyone's got any pointers to results or resources lmk!
Not a full answer but a cute fact. If you want i^i this is the same as exp(i log i) so you first need to know log i. Note that log(exp(i pi (2n + 1/2))) = log i for any integer n, so exp(-pi (2n + 1/2)) = i^i for any n, i.e. i^i has infinitely many values, all of which are real.
