In wild nature, where climatic conditions allow only brief survival on the surface, some druidic orders learned to live mostly deep under the ground, in caves, and they started to call themselves the "Earth dwellers". With so close connection to the earth element, and after long observation, they revealed a strange interference, connected with Earth\'s core. This interference, when concentrated correctly, disrupts manaflow to offensive magic spells and reduce their power as a result. The effect is more powerfull for spells that affect large area, instead of only single person, due to their dispersed nature. After long research, the underground druids created a spell that allows them to concentrate magnetic interference even above ground, and combine it with force and protection of nature developed by their surface brothers. Force of nature can pierce through the interference with raw power, and spells cast by the person ignore the effect completely. Protection of nature spell can use the energy sucked from disrupted spell to boost defenses against further offensive spells for a short time. Individual druids can even cooperate on this spell, to make the interference stronger.
