Quests involved in:
- When you attack a Dredge Blastrock, a small group of Stone Summit dwarves spawns and attacks High Priest Alkar. When you kill the Blastrock, another, larger group does the same.
- Although they are not bosses, killing them gives a morale boost.
- They are much more resilient than normal Dredges, with a high maximum health.
