Hello ENWorld,
Building a Dex-based halfling fighter as a sub-optimal build more for flavor than anything else. Planning on alternating between a hand crossbow and a short sword (with possible back up weapons on hand as necessary).
I'm looking at the Halfling Nimbleness Racial Trait, which allows the ability to move through the space of any creature a size larger. Being a Small sized race, this would mean anything Medium size or larger. Fair enough.
Then looking at the Mobile Feat, which adds 10 feet to your base speed and (in addition to a lackluster Dash Ability) allows you to avoid any AoO against a creature whom you have attempted a melee Attack on (regardless of hit or miss).
If I took this feat, could I hide directly behind a Medium ally (obtaining cover), run through their legs with Nimbleness, use multiple attacks to hit my targets (and maybe peppering in a bonus Hand Crossbow Attack if I later grab Crossbow Expert), then get to scamper back behind my ally into cover, all without incurring any AoO (assuming I melee Attack all possible attackers)?
If it is possible, would this be a worthwhile tactic and/or Feat to invest in?
Thanks in advance for the feedback and I apologize if I have missed anything of import in my post.
