To be honest some of these feats have been requested before, but this is my take on them.
Digging:
You can dig through soil with ease, akin to that of a worm or mole.
Cost: 1
Prerequisite: None
Effects:
You gain a tunnel speed equal to your base speed, and don’t have to make checks to dig through natural soil.
Multi-Armed
You have at least one extra set of arms. Whether through genetics or a science experiment, you can carry more than the average person.
Cost: 2
Prerequisite: None
Effects:
You can carry more than two items at once, including weapons. Extra weapons of the same type does not grant any more advantages for dual wielding.
Dark Vision
You can see in the dark, like a creature of the night, or a cyborg with robotic eyes.
Cost: 2
Prerequisite: None
Effects:
You can see up to 60 feet in the dark. Unlike Blindsight this feat does not help you counter invisible or blindness.
Attach:
Whether through grappling, merging, or digging in, you latch on to a larger target. This is akin to being a smaller creature, like a parasite, mosquito, or a normal size human climbing onto a giant.
Resist ends (special) (Fail x 3 = 1 minute)
PL 1
Attributes: Alteration, Might, Agility.
All Vs Guard
Effects:
You attach yourself to a target at least one size bigger than you, whenever that target moves, you remain adjacent to it. If the target is only 1 size category bigger it suffers from the slowed bane, if the target is more than 1 size category bigger, than it walks as normal. While Attached to target, you gain +1 Advantage to Attacks, Banes, and Boons to the target.
With feats like flying, swimming, and climbing, I feel like any racial ability that is more powerful than a quirk should be made into a feat. So I wish there were more of those.
Let me know if any of these are very similar to other things, or if they seem under/over powered.
