The D&D 5e Player's Handbook states:
Open Hand Technique
Starting when you choose this tradition at 3rd level, you can manipulate your enemy’s ki when you harness your own. Whenever you hit a creature with one of the attacks granted by your Flurry of Blows, you can impose one of the following effects on that target:
• It must succeed on a Dexterity saving throw or be knocked prone.
• It must make a Strength saving throw. If it fails, you can push it up to 15 feet away from you.
• It can’t take reactions until the end of your next turn.
Let me understand this correctly: a monk need only spend 1 ki point to make two unarmed strikes as a bonus action AND impose a Dex save from his opponent (regardless of size) with each of those attacks?
Let's say a halfling monk squares off against a large creature, an ettin for example. The monk spends 1 ki point to flurry, hits the ettin with the first of these two attacks and decides to impose a Dex save. The ettin saves and then the monk attacks with the second of the two attacks, hits the ettin again, and then can impose another Dex save lest the ettin fall prone? Is this right or is there something I'm missing?
If this is indeed correct then it could potentially lead to some terribly unbalanced encounters, all beginning as early as 3rd level (when a monk gains access to this method).
