Spores

After half a day of travel, the Team had traveled through the forest that surrounded their home city and found themselves in a land of rock and rubble. 

Compared to the lush forests they had just been a part of, this place seemed to be teeming with death. The sparse plants they found planted in the hardened land were withering and half dead. The sun beaded across their heads, bearing toward them with untold pressure now that the tall canopies could no longer protect them. And, the air seemed to hold miniature particles of dust that made them want to cough every so often. 

"Don't breathe too heavily. In fact, if you can help it, don't breathe at all." Giveon warned. 

This dusty air was both the source of the Mountain Barbarian's strength, but simultaneously a poison to practically every other creature.
