Make druid guild available to nomad background, but because nomads lack spell
points, they would have to cast wither, quake and other high level spells (to
which they lack sp) by using ingredients.

They could use skulls, bones, powders, liquids, salves, roots, berries, animal
droppings, internal organs or whatever else and using those they could cast
the spells without spell points. Of course the more powerful the spell, the
more it would need ingredients and the rarity of ingredients could vary too.

Perhaps some skills would be needed that concentrate on finding different
ingredients, and mixing them to create the substance needed for a spell to be
cast...

The point of this idea is to bring forth the shamanic perspective of nomadic
life. Unless, of course someone is coding the guild of shamans already. This
would also be a slight uptune and add some flavor to the boring guild of
druids, whether the player is good relig or nomad.
