The Warchief asked me if there's anything we can do about that. I told him, 'You bet we can!'. I was thinking maybe you could take this satchel of grenades and detonate the land mines from a safe distance.
It's how we do things, right?!
Progress
Boss, do you think you could go back down there and detonate a few more?
Thanks!
Completion
Score one for the goblins! Stupid dwarves and gnomes.
Pick up Repel the Paratroopers and The Heads of the SI:7 before heading out. Plenty of mines along the beach. It's helpful to keep the Grenades on your action bar, as they are still usable after you have completed, but not turned in, the quest.
