Flexile Sentry is a Boss in Dark Souls 2 (DKS2). The Flexile Sentry, a merciless creature designed to punish the Undead, is a terrifying lizard-like overseer that manages the ferrying of the undead into the Lost Bastille. Bosses are unique and challenging Enemies that drop Boss Souls capable of being transformed into powerful Weapons, Spells, and Items for the player.

Flexile Sentry Information in DKS2

Flexile Sentry is a boss in Dark Souls 2. Fought below the deck of a ship, this boss is a conjoined warrior with one half wielding scimitars and the other spiked clubs. Attacks rapidly and with speed. The boss will rotate one warrior to face the player and attack with that one, then randomly change to the other side to attack with a different style. Take note that when fighting this boss the room will fill slowly with water but only to the waist. This does impede movement a bit but not to a critical point you can still roll and move about the same speed.

You can find the Flexile Sentry below the deck of the pirate ship that activates after progressing through the level to pull a lever at the far end of the area. Simply proceed up through the buildings and through the long darkdweller mobs (a torch is handy here.) until you reach the illuminated platform with the lever.
When fought on NG+ and beyond, two additional enemies will spawn as soon as the fight begins, they attack quickly, strike hard and aggressively as well as having Ring of Thorns but have low health and should be killed immediately.

The Flexile Sentry is a merciless creature whose purpose is to punish the Undead. This terrifying, lizard-like creature oversees the ferrying of undead into the Lost Bastille.

Dark Souls 2 Flexile Sentry Strategy Tips

• Be very careful while dodging towards the boss. You may end up in front of the other knight who can pull out a fast swing immediately. It is much easier to deal with the boss when it's using the Spiked Club side only, as it's attacks are much slower and more predictable.
  Also, don't take your time when fighting him and try to finish him quickly - the room will start flooding with water until you are about chest-deep in it! This will make movement/dodging/etc. extremely difficult and give the boss a great advantage!
  From NG+ onwards there are 2x Suspicious Shadows in the room with the Flexile Sentry. It is recommend to have at least 1 summon to help you take them out. Take out the smaller minions before fighting the boss. Attack them in between the bosses attacks, he doesn't have any new tricks so he should be fairly easy if you're a competent dodger. ( I used lightning spear with a faith build and i could 1 shot the small minions, great fireball and firestorm were also effective for taking the small minions out)
  
  • For fighting Spiked Club side only:
  The room is a box with a column in the middle.During the fight the room is filling with water. The water rises enough to slow down movements so it's best to finish the fight as quickly as possible. Use the column to avoid his jump attack/regular attacks and then move in to attack during his downtime. His downtime doesn't last long so 1 hit is average. During the attack pattern where he thrusts his maces into the ground you can get two attacks in before he starts up again,
  
  • NG+ Melee only strat:
  Equipment: third dragon ring, chloranthy ring +1, old sun ring, optional -- espada ropera +10 / mirrah greatsword +10 // any 100% phys damage block shield but I used an unupgraded king's shield
  When you enter the room immediately lock on to boss and begin strafing to the right. Keep the boss in your vision at all times and keep the wooden support beam inbetween the both of you, this way if he lunges it will limit his movement. Use the mirrah greatsword so you have a horizontal attack, and as soon as one of the adds jump on you hit them quickly, there is a slight delay before their attack. If you end up taking a hit, the old sun ring should buy you a bit of time to reposition and/or estus. Once the adds are down, get to the spiked club side of the boss and circle his right side. switch to the thrusting sword and wail away, 2-3 attacks after he swings. If you end up taking a hit buy yourself space by putting the support beam in the center of the room between you and the boss. He should go down quickly and with ease.
• You NEED high DPS for this fight. Those two Suspicious Shadow enemies that show up in NG+ and beyond will pressure you. Dual lightning Berserker Blades are a good choice. Dual Lightning Espada Roperas are also good, along with
• This is a high-pressure fight. That means you NEED a weapon(s) with the shortest attack animations possible, but with decent reach so you don't have to walk before attacking.
• You will have more time than you think on NG+7 and CoC. So take the necessary time to kill the two enemies that drop from the ceiling, then focus on the Sentry.
• The Barbed Club half of the Sentry has many more openings for punishment than the Sabre half of the Sentry. Sprint to keep to that side, and hitting on the sides of the Sentry works nice, too.
• For endgame, you wanna do about 900 damage per attack if you wanna survive comfortably. I was pacing well with 550 (Lightning Greatsword +10) but with dual Berserker Blades +10, one Magic and one Lightning, I was doing 900 per attack and it was working fine. Dual Lightning infusions would have still worked better, though.
• Please find clearance and the right boss animation for using Estus. Flexile is highly pressurizing and it is very easy to be hit while using Estus. Similar to Gwyn, you can use the environment to space yourself from him. The wooden pillar in the middle of the room is pretty good at getting the Flexile Sentry stuck, so feel free to use it to give yourself time to heal.
• For endgame, don't worry about the water. It takes a LONG time before it fills up to kill you, and you don't lose i-frames on roll, so if your roll is 16 i-frames, then you've got nothing to worry about. I made the mistake of trying to speedrun the fight by trying to punish every attack, but I ended up dying. After giving up on that, I was chest-deep in water on my successful attempt, and this was NG+7 with the Company of Champions activated.

Flexile Sentry Notes and Tips in Dark Souls 2

• Weakness: Lightning
• Fast roll to win!
• Using Scraps of Life on the decks above the boss fight area near the mast can damage the assassins that appear alongside the boss on NG+ putting them on minimal health, seemed to have no effect on the boss for me but results may vary, other AoE spells may produce similar results.
• Wooden pillar in the center of the boss area can block most of his attacks.
• Due to the water in the arena, as well as the size of the Flexile Sentry, Heavenly Thunder is extremely effective at reducing its health--even more so than Lightning Spear. The central pillar may be used as cover to cast the spell.
