10 Arrow Deflections. This achievement is all on timing. Swinging you're axe just as the arrow makes contact with you causing the arrow to bonce off. Treat it like baseball, rounders etc. Only difference is if you don't deflect the arrow it's going to hurt
The game is NOT dead by any means. EU, US servers in SOLO'S and DUO'S are still very lively, Meaning you can give this a shot against random players if you wish.
Most people that play this will likely use arrows to try take you down. Getting the deflection will be harder at a further distance. So closing the gap between you and another player will give you better odds. Things to look out for is the blue spark that comes off their bow as they are about to shoot. Once you see the spark you'll want to imminently swing your axe getting a deflection. Randoms won't show mercy so this may take a few matches to do. Patience and timing is key.
Boosting Method.Boosting can be done with as little as two players.
Search in SOLO'S. Preferably on a sever in your region. So that their is no lag. Playing in Singapore servers are fine for getting into matches on your own. But at the cost of being super laggy making the timing of the shots a little more difficult to pull off.
Once in a match, pick a zone to meet in. Once you've found each other. Have the person going for the achievement stand still and keep spamming [cn_RT] while the other person stands 2-3 metres away and times the shots with the arrows. You'll want to shoot as they are in mid swing with the axe.
This is a clip I made for example while helping my nephew get his achievement. You can use my distance as a guide on how far apart you should be:
