Domain of Tangle and Root

The Domain of Tangle and Root channels the deep forest, its predators, its almost alien seeming ways to most, and its protectors. The gods of this domain wish for their clerics to protect and conserve the wilds, for them to be left alone, and for the clerics to guard them, sacrifices to the forest creatures and trees, and bury bodies in the soil for them to fertilize the next generation of trees, all of these are part of some of the faiths that guide these clerics. Few deities can claim influence over this domain, due to agricultural gods and goddesses being unable to, as this is specifically untamed wilds, most of the gods that can claim this domain are largely unknown (Acheron, Jörð, Fjörgyn, Aja, Ọsanyìn, Oshosi, L'inglesou, Grand Bois, Abu, Ningikuga, Mẫu Địa, Artio, Selvans, Rán, Nei Tituaabine, Tāne) as well as many powerful spirits (Ngen, Dokkaebi, İye, powerful Dryads or Hags, some Archfey).

Sight of Tangle

When you choose this domain at 1st level, you gain 60 ft of Tremorsense (through plants), proficiency in stealth, and your walking speed increases by 10 ft.

60 ft tremorsense through plants means that you can see, for a 60 ft radius, around the place you are physically touching on the plant, through the plant to feel what else is touching that individual plant or any other plant that that plant is touching. 

Force of Claw and Hoof

Also starting at 1st level, you are bonded to the deep forest and its apparent dangers to those not accustomed to it.
