because (a) all of his other destructive powers are aimed at monsters, not the player; (b) it's probably in for symmetry with Xom, but since Lugonu was added to the Chaos God sub-pantheon and doesn't have it, it's no longer as fitting; (c) among Makhleb's "Greater Destruction" effects, the orb-of-electricity effect covers electric attacks nicely; and (d) Xom's effects are generally not conjurations-oriented, except for divine lightning, and making it unique to him is good.
