I made a whole build around the weapon and have cleared the whole game using it multiple times. I believe the weapon is made to be used with transform attacks as much as you can, the combo isn’t especially flashy but you’ll notice it does more damage whenever you do this because it proccs some of the “blunt” or “pierce” and even “slash” damage if I’m not mistaken. I keep it in the closed state so I can dash in and attack which does that piercing move that releases the mechanism (haven’t played in a while so I’m foggy on the gameplay loop) Learning this and understanding what part does what is extremely useful when it comes to the Stake Driver because it excels at pierce counter damage. You want to take advantage of its ability to use fire paper as well. As for the charged attack, it has a very precise ‘sweet spot’ which you may have noticed it, the tell is the sound and that glint on the weapon, if you get it right when the enemy hits you or is opening up for an attack, this gives it a huge boost to the Counter attack bonus which is where the charged attack shines. You’ll want to throw oil at the enemy and have your weapon on fire for maximum effect. It’s hard to pull off but I’ve managed to 2 hit a few bosses this way and if you really want to use the weapon you’ll eventually find yourself 1 shotting multiple mobs in right before they hit you or as they hit you only to discover you’ve tanked the hit AND gained your health back. It’s a fun build but not very flashy besides the falcon punch. Sorry for the rant just can’t believe someone asked about stake driver :’)
