I use the following feat. I think I based the feat on one I read about somewhere, but no idea at this point where or by whom.
Prodigy
You are a master of two paths and your ability to think outside the box and innate affinity to your class has allowed you to learn to blend training from more than one subclass of your class. You gain the following benefits:
- You gain proficiency in one additional skill or tool of your choice from your class list.
- Choose a second subclass from a class you already have levels in and that has more than one subclass. Doing so grants you the following benefits:
When you gain a new feature from your subclass after taking this feat, you may choose which of your subclasses to gain features from. (You do not gain the benefits of both). You are considered to be of that subclass until the next level at which your subclass grants a feature (this pertains to abilities the subclass grants in between feature levels).
For example, a Druid could become both a Land and a Moon druid. At 2nd level, you could choose to gain either the Circle of the Land features (Bonus Cantrip and Natural Recovery) or the Circle of the Moon Features (Combat Wild Shape and the 2nd level benefits of Circle Forms). If you choose Land druid, you also gain Circle Spells at levels 3rd and 5th. At 6th level, you can again choose between Land (Land’s Stride) and Moon (Primal Strike and the 6th level benefits of Circle Forms). If you choose Land at 6th level, you will also gain the 7th and 9th level Circle Spells. At 10th level you can choose between Nature’s Ward and Elemental Wild Shape, and at 14th level you may choose between Nature’s Sanctuary and Thousand Forms.
As another example, a Fighter could choose to be both a Champion and Eldritch Knight. At 3rd level assume you choose Champion, gaining Improved Critical. At 7th level, you choose Eldritch Knight, gaining War Magic and Spellcasting. However, your spellcasting starts as per a 3rd level Eldritch Knight, because you were not an Eldritch Knight from levels 3-6, and therefore did not gain the benefits thereof. At 9th level, you will have the equivalent casting of a 5th level Eldritch Knight. Continuing on, at 10th level you take Champion, gaining Additional Fighting Style. Once again, because you are not an Eldritch Knight during this period, your Spellcasting will not improve from levels 10 to 14. At 15th level, you once again switch to Eldritch Knight, gaining Arcane Charge and improving your Spellcasting to the equivalent of a 6th level Eldritch Knight. At level 17, your Spellcasting will have improved to the equivalent of a level 8th level Eldritch Knight (allowing you to choose one spell from any school of magic, per your Spellcasting feature). If you choose Eldritch Knight at level 18, you gain Improved War Magic, and by 20th level you will be the equivalent of 11th level Eldritch Knight in Spellcasting ability. If you instead choose Champion at 18th level, you gain Survivor and your Spellcasting capabilities will remain the equivalent of an 8th level Eldritch Knight.
