Elongation
You can elongate your body and/or limbs to extend your reach. This Growth only changes your size. Morph (1 rank) is required so that your size does not need to be proportional. This doesn't allow you to shrink below your normal size. See Growth for the benefits of changing size.
You can use Elongation to make "close" ranged attacks at a greater distance by elongating your limbs. Once elongated, you can make melee attacks within your new reach as a standard action. If you can't accurately sense your target (you're elongating around a corner, for example), apply the rules for concealment (see Gameplay Rules: Concealment). In addition, Elongation allows you to wrap up and entangle an opponent so it grants a +1 bonus to grab checks per rank (limited by PL).
