Alright so right quick, two attacks are going to hit you, first is from a goblin, just a regular hit from his scimitar. Second one is the ogre's javelin, he hits with a 22 and will do 9 points of damage. You can lucky this if you want, or you can even try and deflect arrows (Technically the javelin counts as an arrow in this instance). 1d10+dex+monk level, you might got this!
