Just did this part. Maybe somebody else had same idea but I spawned wind-up toy, feather-falled it close to totem (don't move otherwise the toy will follow you), just before the explosion I turned my characters invisible just in case = mission accomplished. Maybe you can even spice it up by making the toy invisible. I also spawned fire-elemental close to the totem and as it expired it set the totem on fire and eventually it got destroyed, again the goblins didn't seem to care. I bet there is bunch of other ways.
