Hey people, a question about the feat switch by Fred.
I would level, let's say, to the 15th with dex 16 and taking a feat, let's say toughness.
Then i want to eat a +4 dex tome bringin' my dex to 17.

If i try the feat change, can i choose improved two weapon fighting (ofc i already have the two weapon fight feat) instead of the toughness feat?
