Grapple

A Grappled creature's speed becomes 0 until the
target is released, escapes, the Grappler becomes
incapacitated, or the creature is removed from
the Grappler's reach.
Spend your Action and attempt to grab/wrestle
a creature. Make one Attack with at least one
free hand that resolves against a target within
your reach, and no more than one size larger
than you. Make an Athletics check versus the
target's Athletics, or your Acrobatics versus the
target's choice between the two.
