Hobshroom

A shroom that is a fire red in colour and is a goblinoid delicacy, although it causes moderate stomach pains in most other humanoids. It typically grows in areas inhabited by giant spiders, sprouting from decaying webbing, which is the perfect fertilizer for this fungus.
However, for the fungus to continue to prosper, it must be regularly supplied with old webbing to feed on. Its for this purpose that more organized tribes, or even legions can be observed to reserve cave chambers for the purpose of housing giant spiders, both for their venom and the Hobshrooms.

Can be included in the process of poison crafting to increase the DC of a poison by 1D4 to create an up to +4 poison.
