Unless Mental Leap is overkill, a daggoran can have this (as a bonus feat).Combat: Daggorans can opt to jump up to their movement distance. This hop will clear any object up to one-third as high as the length of the leap and requires only a single round to accomplish. A jumping daggoran can attack in midair or at the end of its leap.
Detonate can be modeled on either hail of crystals or swarm of crystals, but I favor the former:In the wild, when a daggoran comes upon a potential meal it usually launches an attack with its detonate psionic ability (which originates from the crystalline growth on its back) at the ground near a victim, sometimes killing it with the shrapnel created from the explosion. If the victim survives the initial attack, the daggoran rushes in to attack with its mouth, causing 2-12 (2d6) points of damage per hit.
