Natura Ferina - 5E CR15 Legendary Monster

Natura Ferina

This gigantic creature looks as if the ground suddenly stood up and started walking. It is made up of dirt, grass, shrubs and small trees.

The Natura Ferina is the embodiment of wild, untamed nature. When civilization encroaches too much into the wilderness this creature is born and seeks to set back that which communities try to build. In all such cases, the natura ferina hunts the despoilers of nature.  

   A natura ferina comes about in a number of ways. Some spawn spontaneously when the depredations caused by the exploitation of civilization become too much for the land to bear. It is also said that some individuals that are close to nature, such as druids or elves, know of rituals that can summon the natura ferina. However, in either case, a natura ferina is born in hatred, hatred for those who exploit the land.

    Note that there is only one potential natura ferina for a given region. Once it is killed, it cannot be summoned again. Once the land has been cowed it succumbs to those who seek to use the land. Also, a natura ferina will not always spontaneously appear; sometimes the taming of a wild land is slow and measured and does not raise the ire of the land until its spirit is already too weak to do anything about it.

Lair Actions

The lair of a natura ferina is anywhere there is land, so they will most be in their lair. A natura ferina is one challenge rating higher while in its lair; Challenge Rating 16 (15,000 XP). On initiative count 20, the natura ferina can take one lair action to do one of the following:

·         A 20’ cube within 90’ of the natura ferina collapses leaving behind a 10’ pit. Anyone in the area must make a DC15 Dexterity saving throw or fall into the pit taking 1d6 falling damage. The sides of the pit slide back into the pit so a check to climb out requires a DC18 Athletics (Strength).

·         A 60 foot area centered on the natura ferina becomes difficult terrain.

·         A 20’ cube within 90 feet of the natura ferina comes alive as the grasses and roots try to grab enemies. Anyone in the area must make a DC18 Dexterity saving throw or become restrained. It requires an action from the target or an ally and a successful DC18 Strength check to break free. 

Regional Effects

The area near a natura ferina is wild and untamed. This changes the region as follows:

·         The area is considered to be difficult terrain.

·         Roads, trails and markers within 1 mile of the Natura ferina shift and change randomly.

·         Within 1 mile of the natura ferina, it is able to detect large groups of creatures (10 or more).

·         Animals not normally aggressive will become antagonistic toward humanoids. Smaller animals will not attack as they know they cannot prevail. However, larger animals may attack.
