Gyrm is excellent for tombs. You get a speed boost and great damage. The only downside to gyrm is that he doesn't give a considerable amount of health (use your clocks and stuns wisely). When soloing tombs, it is important to kill the mages off fast before they summon skeletons and with gyrm's aa providing a massive crit boost, you can ensure that your first clock and fireball will hit HARD. Gyrm has a multi-combat attack like Ethyl, so that helps as well.
