Lords of the Fallen (2014)

This might be possible on the 2nd boss but I'm not sure. You can definitely get this from the Beast boss fight in the same area but later in the game.

I tried for a long time to get him to charge and destroy the statue without success.

To get it what I did was use my Shard of Heroes found in a hidden area at the start of the game on one of the statues, normally if you use that shard you will be given a chance to respec but if you use it in the boss fight you will get a weapon, here you must use it during the fight.

Now I died after I use the shard and still got this so don't worry if the same thing happens to you.
Once you take off the 1st section of the Beasts health he will deliberately walk over and smash whatever statue you used , the achievements won'y unlock until he is dead.

Now I tried without success for over an hour to get him to charge the statues and break one even using the prayer spell to lure him to it , I'm sure it should be possible just I had no luck and my way you are certain to get it if you have the shard.

SLaymatrix added this video in the comments that shows how to get the shard and achievement (not my work)
I should also point out if you do not have it when you meet the the boss then I do not think it's possible to back track to get it at that stage, I think you would have to kill him to do that.

One more thing if you do it my way don't forget to go to the broken statue after the fight , there will be a weapon for you there!!!!! You have a choice of statue each with it's own weapon so choose one that suits your character , think the choices were dagger , sword , and hammer.

Feel free to add to the comments and I will update the guide.

UPDATE: JP4YT0N has confirmed in the comments that this can also be done in the same way against the commander boss , this means that if you missed it you will only have a very small part of a new game to replay in order to get to that point, thanks JP4YT0N
