The following works with PC patch 1.01a.
During level up at the attribute screen first ADD points to the attribute you want to eventually take away from. Then press the "Reset" button. Now you can take away the number of points you added from that attribute and redistribute to a new attribute.
For example; lets say your character has 16 str and 16 dex when you level up. You want to take 3 dex away and add it to str. First add your 3 level up attribute points to dex bringing it to 19. Press the "Reset" button, which brings it down to 16. Now press the left arrow by dex 3 times to bring it down to 13. Now reassign all points to str.
If you want to reassign more than 3 points at a time, first add 3 to an attribute, press the reset button, add 3 three to the same attribute and repeat. Afterward when you press the left arrow by the attribute you'll be able to subtract the total number of points you added.
