Ashardalon’s Stride is making my current Wizard/Arcane Trickster drool. 50 movement speed (60 with Longstrider), free disengage (so bonus actions can be used to dash or hide), and 1d6 damage to anyone that I get within 5 feet of? That's an amazing spell for him.
Also, the other character I'm running on the off time for the primary DM is a Ranger who just hit level 3. I'm really struggling now between Swarmkeeper and Drakewarden for my Eberron Ranger.
Overall I'm very satisfied with this release. I know some people don't like the Monk nerfs, but it is still a solid Monk subclass (and Monks have always been one of my favorite classes). Drakewarden is good, the feats are a solid addition, the spells are a solid addition. I'm very happy with it.
