If you don’t want to multiclass, but you want some spells, let’s add some feats to build on this idea!

Magic Adept

Prerequisite: Magic Initiate

For the class you choose for Magic initiate, you gain the following:

• Gain two more cantrips
• Learn three more 1st level spells and the ability to cast two more 1st level spells before you must take a long rest.  You may cast the same spell more than once but each spell you cast uses a 1st level spell slot from Magic Initiate or this feat.
• Learn two second level spells and the ability to cast one second level spell from this class.

Thoughts?

I know you can grant advantage to a friend as an action, but what if you could do it as part of a strike?

Face Strike

You go for the face to not only cause pain, but to distract your foes for your friends.  Gain the following benefits:

• Increase your dexterity or strength by 1 to a maximum of 20.
• When you make an attack with a weapon, you can take a -5 to the attack roll.  If you do and the attack hits, you damage the creature as normal, but the next ally to attack the target has advantage.

Thoughts?

If your hemmed in by kobolds on all sides, you want a friend for your back!  I think two fighters who know what their doing should be able to do some pretty impressive stuff.  Let’s make that happen!

Back to Back

You and your friend have trained to perfection to keep each other alive.  As a bonus action, you can activate this feat.  If you are engaged with another ally who has activated this feat, you both impose disadvantage on any melee attacks and spells with the touch descriptor either of you receive till the end of your next turn.

Thoughts?

One last DnD 5e feat for a bit.  I like the downtime mechanic, but I’d like to build on it.  How about a feat to be quicker at applying it?

Quick Study

You are a very quick learner picking up skills that would take years to master in weeks.  You’re nimble fingers make any time you would take to fix gear and build things pass in the blink of an eye.  When you use downtime days to do any activity or training, the amount of days and money necessary to complete the task is cut in half.

Let’s keep the hits rolling with a new idea for Goliaths

The Stone People

You are the bedrock your people build upon.  You can not be stopped, only slowed.  Gain the following benefits:

• Increase your constitution or strength by 1 to a maximum of 20.
• Your stones endurance increases to 2d12.  At level 5 it becomes 3d12.  At level 10, it is 4d12. At level 15, it is 5d12, and at level 20, your stones endurance is 6d12.  You must still take a short or long rest to refresh this ability.

Thoughts?

The Deep Gnomes get a feat, but the other races don’t from the Elemental Evil Player Companion?!  Let’s fix this problem!

Genasi Focus

Prerequisite: Genasi

You are a paragon of your race.  A person truely chosen by the elements!  Gain the following benefits:

• Increase to the same elemental specific statistic you normality gain a bonus from at character generation by one.  As an example a Air Ganasi would gain a +1 bonus to dexterity.
• The elemental specific spells you gain at character generation now can be reused after a short rest instead of a long rest.

Thoughts?

With people flying around, someone is going to want to fly in some armor.  let’s make that happen!

Armored Flight

Prerequisite:  The ability to naturally fly with wings

You have worked hard to strengthen your wings to carry even the heaviest of loads.  Gain the following benefits:

• Increase your strength or constitution by 1 to a maximum of 20.
• You may now fly with any armor you are proficient with.

Thoughts?

The Aarokacra can fly!  Devils and dragons have wings too.  Could a tiefling or a dragonborn get wings?  Maybe…with a feat

Flight Mutation

Prerequisite: Dragonborn or tiefling

Deep in your family history are flying beings, and you’re lucky enough to gain that too.  You gain wings that allow you a flying speed of 50 and to hover.  You have to spend an extra 25% of any armor or clothing’s cost to modify the armor or clothing to fit you.  This is not true for magic items as they resize for you.  You may not fly with heavy or medium armor.

Thoughts?

You can charge and do damage.  What if you could stand tall and hold a position?

Hold Your Ground

You are a wall!  You don’t move the fastest, but you no one moves you or around you.  Gain the following benefits:

• Gain +1 to your strength or constitution to a maximum of 20.
• Gain advantage on any saving throw that would move you.
• When you don’t move for a turn, gain a +1 bonus to your AC and any attack you make.
• When a creature moves to engage you in melee, as a reaction you may make an attack against that creature.
