Monk - burns reaction catching arrow

Dm - "and now they turn the balista on you"

Monk - O_O

I once let our monk deflect a ballista bolt because he said he was going to do the redirecting with his flying kick instead of his hands, so I had him roll acrobatics with disadvantage since his reaction time would have to be through the roof to pull it off.

rolled two nat 20's. Not only did that ballista go sailing right back at the machine that fired it, it utterly destroyed it and the three dudes manning it, because after kicking half a telephone pole back at your enemies, you've earned the right to walk away from an explosion without looking at it.

I also made him roll to see if he hurt himself landing and he did, so he had to deal with a bad ankle the rest of the encounter (-3 dex, I am a jealous god)

Yes! Shoot your Monk is standard GM advice! they took those powers to look badass, just give them one useless archer per combat and they will shine! And throw arrows!

And if you still want to throw them a curveball you can always throw in the occasional bit of exotic ammunition that messes with them when they catch it (Use sparingly so they still get to feel cool)
