The new Order cleric looks extremely strong, not just as a domain for a straight cleric but as an excellent one-level dip. Adding a reaction attack to any of your spells which target an ally will really help to improve party damage, especially if you're supporting a Rogue. The effect works with spells you're probably already using, like Healing Word, but you can also have your ally make a standing high jump (which has a height of 1.5 feet, assuming 10 Strength) and cast Feather Fall on them as they start to drop, which allows you to use your reaction and a level 1 spell slot to grant someone else a reaction attack on command. Probably not the best use of your slots outside of supporting a Rogue, but pretty funny.
