In your exploration of Tamriel, you find a very rare artifact: Hermaeus Mora's Tome of Inexplicable Knowledge. What does it do? Well I will tell you, dear reader!
It presents you with a choice: Ignore the tome and proceed normally OR sacrifice your second skill bar and the ability to weapon swap in exchange for the ability to choose ANY five skills and any one Ult, from any class skill line. Passives are not affected. You have to only use these six skills for the duration of the effect, which is.... Oh let's say one week.
So only one bar with any five skills and any one Ult at the expense of weapon swapping and an extra bar.
Do you do it? If so, what six skills do you choose?
