Daily Punch 6-17-15 Speed of Thought Feat for DnD 5e

Let’s keep building on the dual save feats.

Speed of Thought

You can either out think your opponents or simple out move them.  Maybe it’s a bit of both.  Gain the following benefits:

• Dexterity saving throws can be made using your Intelligence modifier, and Intelligence saving throws can be made using your Dexterity modifier.
• If you add your proficiency bonus to both Dexterity and Intelligence saving throws, add 1 and 1/2 (rounded down) your proficiency bonus instead.
