Dullahan Boss Moves and Counters
What this page helps you decide: which of the Dullahan's four moves you dodge and which you simply walk away from, since two of them punish a dash.
The Dullahan is the boss whose moves are modelled on the player's own. Powerful Slash is described as a weaker version of the player skill of the same name, and Wave Slash as a faster version of the player's wave attack. It has a small health pool and can be traded down if you have a life to spare, most of its attacks are aimed directly at you, and the Beastiary notes the areas it is fought in are usually cluttered with props, recommending area damage to open. The move to respect is Powerful Slash, which has a long wind-up but no ground indicator at all - the only clue is the boss raising its arm without a marker appearing - and the counter is distance rather than a dash.
Two attacks, two opposite movement answers
This boss is a good test of whether you are reading attacks rather than reacting to them. Wave Slash is answered by a side dash. Powerful Slash is answered by walking out of range, and dashing is specifically not recommended. Both come from a boss that is aiming most of its attacks straight at you, and one of them has an indicator while the other does not. The practical consequence is that you cannot fight this boss on autopilot with the dash key: you have to identify which attack started. That is the same lesson the Vampire's Pulse teaches at elite level, and this game teaches it twice, which suggests it is deliberate design rather than an oddity.
Standing still is a tactic here
The hand of ghoul triggers when you are stationary: a straight line indicator appears on the ground and a slow, oversized hand sweeps along it dealing high damage. Because it is slow and telegraphed, the Beastiary treats it as an opportunity - baiting it means you know exactly what the boss is doing for the duration, and it is not doing anything else. That inverts the usual advice about never standing still. Against the Cannon Yeti, standing still is lethal. Against the Dullahan, it is how you choose which attack you face. Knowing which enemies reward which behaviour is most of what the Beastiary is for.
Small health, and a mirrored slam
The Beastiary notes the Dullahan's health pool is small and that you can simply trade it down if you have a spare life, which is unusual advice for a boss and reflects the fact that most of its damage is single-target and readable. One more comparative detail is published: its slam resembles the dragon's, but is biased toward the boss's right side, while the dragon's leans left. That is the sort of thing that only comes from someone testing both fights, and it is the kind of detail that no competing site carries - the largest competing boss database contains a single entry for the entire game, marked as needing testing.
Step-by-Step
- Open with area damage. The published note is that the surroundings are usually full of props and the situation is generally poor, so clearing space first is the recommended opening.
- Stand still deliberately to bait The hand of ghoul. When you are stationary a line indicator appears and a slow, large hand sweeps through with high damage - and the Beastiary calls that a good chance to attack it.
- Watch for a raised arm with no ground indicator. That is the only tell for Powerful Slash, which has a long wind-up and high damage.
- Beat Powerful Slash with distance, not a dash. The page is explicit on this: get away from it rather than trying to dodge through it.
- Side-dash the Wave Slash. That one is a faster version of the player's wave attack and a lateral dash is described as the best answer.
- Do not rely on rhythm. Its Roll has a very short cooldown and exists to close distance or evade, which the Beastiary notes disrupts your timing.

Tips & Notes
- Its slam is biased to the boss's right, where the dragon's leans left - a difference worth knowing if you learned your spacing on the dragon fight.
- Because most of its attacks target you directly rather than covering an area, positioning relative to other enemies matters more here than positioning relative to the arena.
- This is one of three bosses with no published map assignment, alongside Wereworld and the Executioner.
FAQ
How do you dodge the Dullahan's Powerful Slash?
By distance, not by dashing. It has a long wind-up but no ground indicator, and the only clue is the boss raising its arm without a marker appearing. The Beastiary specifically advises getting away rather than dodging through it.
Should you stand still against the Dullahan?
Sometimes, deliberately. Standing still triggers The hand of ghoul, which paints a line indicator and sweeps a slow hand along it - the Beastiary describes that as a good opportunity to attack the boss.
Is the Dullahan hard?
Its health pool is small and the Beastiary says you can trade it down if you have a spare life. The difficulty is that its two slash attacks require opposite responses and one of them has no indicator at all.
