How to prepare for the Focused Fault boss fight in Darkest Dungeon II

Before you go toe to toe—or eyeballs to eyeballs—with Focused Fault, you will need to prepare thoroughly for the fight by making sure you’ve taken care of some essential prerequisites.

One of the first things you can do to make your time against Focused Fault easier is by leveling up your heroes to ensure they possess the necessary attributes and skills to take on this formidable boss relatively easily.

Another important aspect to take care of before taking on the Focused Fault is increasing all relationships as much as possible as positive relationship boosts can increase Heal and decrease Stress during the battle, which can most certainly make or break the entire boss fight for you.

When preparing to leave the Mountain, there are a few things you can do to optimize your readiness for the Focused Fault fight. They are:

  • Buffing all your heroes with the best food you have at your disposal.
  • Reduce the Stress of all your heroes.
  • Heal your heroes as much as possible.

When it comes to Inn items, you will want to purchase ones that increase your Stun resistance, debuff resistance, and healing. A few of the items that will do these exact things for you are:

  • Oddly-Tuned Lute (Jester signature item).
  • Clarifying Poultice. 
  • Mop and Bucket.

While we’re on the topic of items, you should definitely be utilizing combat items as they are the best option you will have at your disposal for getting rid of the multiple debuffs inflicted by Focused Fault. You will also want ones that get rid of the eyes’ Dodge.

Keep in mind that all the stalks as well as Focused Fault have some resistance to each damage-over-time type, so having those stacked can keep the damage going while your party heals itself.

How to beat the Focused Fault in Darkest Dungeon II

Phase One strategy: Stalks

The four stalks start the fight with high speed, applying one of each Seen Token on each hero, mirroring their positions unless they are forced to target another hero. Seen Tokens are the key to the entire boss fight, acting as a Horror effect as well as a target for the Focused Fault’s brutal attacks.

If all four heroes are marked, you will incur upwards of 60 damage per turn on your entire team, which is not feasible for your success.

The solution is to move your heroes around all the positions so the Seen Tokens all end up on one person. Other options include moving the eyes themselves with disruption skills and using Guard abilities.

Killing a Cloistered Eye will remove its respective Seen Token, but the Stalk will return the next round. If you leave the Cloistered Eyes alone for long enough, they will grow into Bifurcated Eyes, and then into Cluster of Eyes. Once all four stalks reach their maximum level at the same time, they will bring forth the Focused Fault.

Phase Two strategy: Focused Fault

Your main focus (no pun intended) for Phase Two should be on damage mitigation and haste. Focused Fault will strike anyone marked with Seen Tokens with disgusting amounts of damage along with applying a debuff that lowers healing received from all sources by 25 percent. Since you need to defeat the boss before it wipes your team out, damage mitigation is key.

Abilities and effects that can apply Dodge and gain Block or Weak can assist the targeted heroes and keep them alive for another three to four rounds before they start to melt down from Horror and Stress.

The good news is the Focused Fault possesses no Deathblow resistance, and neither does it have good DoT and Debuff resistances, which makes having high damage per turn on your team crucial to beating the second phase. Since it has two turns per round, DoTs proc more often as well.

Plague Doctor’s Blight, Runaway’s Burn, or Hellion’s Bleed act as simple ways to apply threatening DoTs. Heroes with side DoT effects like Graverobber’s Poison Darts and Highwayman’s Open Vein are good choices as well.

Another thing you need to keep in mind is Suppress, which applies a slew of negative Tokens onto your heroes, including Stun. Make sure you don’t focus entirely on dealing damage and give your damage-focused heroes ways to remove or ignore effects from skills like Suppress.

Remember, Focused Fault is an incredibly tough boss, so even if you fail after a few attempts, make sure to keep applying what you’ve learned and continue trying your best.
