Non units can't be damaged by the Firebreather's fire attack or the Chander's vomit
Making them extremely bad at dealing with anything a non-living creature. They can't even knock enemy doors at a decent pace as other creatures. And bad assaliants for the Dungeon Core.
Can not confirm that.
Both attacks deal damage against Defenses.
Tested it with lvl 5 Chunder and FireBreather against Ramparts.
