Last week, I created a faction of rangers who watch over portals, a group that calls themselves Those Who Walk Between. Today, I'm going to stat up one of them as an enemy.

They're inspired by the Horizon Walker Rangers from Xanathar's Guide to Monsters, and I want to re-use several of the abilities there: Detect Portal (duh), Ethereal Step (the ability to cast etherealness as a bonus action, but it only lasts this turn and recharges after a short or long rest), and Distant Strike (teleporting up to 10 feet before each attack). The Planar Warrior feature is basically extra damage, and while it's cool flavor we can wrap that into the creature's attacks. It also gets several spells that I'd like to find a way to use.

As a basis, I want this to be a CR 10 enemy (Distant Strike is a level 11 ability, so we'll shift something else down slightly to accommodate it), and something similar to a regular humanoid. The CR 10 Deva is quite close to the concept, so let's start there.

Let's look at the deva's abilities. We can swap out the angelic nature of its weapons with force damage, replicating the Planar Warrior feature. That leaves us with Healing Touch and Change Shape. I'm comfortable swapping those out with Ethereal Step and Distant Strike, while also giving it Detect Portal in exchange for removing the condition immunities and its resistance to radiant damage.

Conveniently, the deva can also cast three spells, so we'll just swap those out with the spells that the Horizon Walker gets.

The basic ability scores for the deva are bonkers, but we do want these to be very experienced characters. We'll keep the high strength, dexterity, and wisdom, but lower the constitution and charisma to more normal levels. Similarly, we'll swap out the higher charisma save for a higher dexterity save.

That'll do it! Let's stat it up.
