I play a Druid Circle of the Land. Therefore I have the Land Stride capability.
The question came up when I tried to move through an allies space.
The PHB states "Remember that another creature's space is difficult terrain for you."
However, Land Stride states, "Starting at 6th level, moving through nonmagical difficult terrain costs you no extra Movement."

My obvious question is, can I move through a friendly creature's space without penalty ?

I would say that's up to your DM, but I'm a D&D noob.

Hmm, thats a bit of a tricky one.

I would make moving through creatures spaces still cost extra movement, because that is what I think is intended. But I think RAW it wouldn't.

Thanks.
My DM says he's thinking about it. LOL

Personally, I would say that Land's Stride would allow you to treat another friendly creature's space as normal terrain, so you wouldn't spend extra movement in it. This is because as a friendly creature, they would obviously not try to hinder your movement, so you would just need to step around/over them (depending on if the're prone), whereas a hostile creature would try to hinder you.

So, I would say no extra movement cost if the creature is friendly, but ignore Land's Stride if they are aggressive/hostile.

Also apply Land's Stride if the creature is dead or unconscious.

Finally, remember, you could still not stop in the same space as a creature (though I would allow it if the creature is dead).

I was thinking of it like this.
The reason that you have Land Stride is that you have learned to be very agile, turning your body in such a way to avoid vines, needles, thorns, rocks, overgrowth, rough ground, and the like.
So I think you'd also be able to turn your body in such a way to avoid friendly bodies that are in your way.

Thanks everyone for your input.

You hit the nail on the head, that is how I see it as well.

The Druid being a "one with the land" class rather than a agile, acrobatic class like the Rogue, I tend to think of Land Stride as the Druid having such an affinity for plants, the earth, and objects made of those substances (which includes furniture and, to some limited degree, organic creatures) that they actually get out of the way for her/him.  There is no action required on the part of the Druid.  Just my 2 cents on narrative flavor.

Thanks

I really like that perspective.

It really takes in consideration how the Druid developed the Land Stride ability.

Lots of great responses, let's see which one my DM excepts.

He is a demigod after all.
