Jack of the Same Trade

Skilled at several things you gain the following benefits and abide by the following restrictions.

• You swap out a subclass feature from a subclass you have, level three feature's and under, and take a new one, only a feature gained when normally choosing a subclass, from a class you already have a subclass in. When the old feature is swapped out for the new one you loose the old feature and it's associated benefits and they are replaced with the new feature and it's benefits. You can not take a subclass feature in this way from a class you do not already have a subclass in. Subclass features that scale based on your level in the class are treated as scaled to the level the features is normally gained at, for example since subclass features are given to Wizards at 2nd level, the THP gained from Arcane ward is locked at two times 2 + your Intelligence modifier rather than scaling with your wizard level.
• When taking this feat one ability score, of your choice, gets a -2 to it's base score (Can go under 8).
• When taking this feat if you already have a Savant Wizard feature you can not take another one.
• This feat can only be taken once. 
• This feat can not be taken for another bard subclass feature. 
• This feat can not be taken with a homebrew class or subclass.
