A special fungus gathered from the wilderness or cultivated in the Growth Chamber. Promotes Lv.60 operators.
Every year, many frontier settlers would suffer multiple organ failure caused by ruby bolete poisoning. This often results from misjudging the edible stage of the fungus. Eating the fungus in ruby stage is extremely dangerous.
