Adel Expedition Duchess Build

Intro

Duchess, unlike some other characters, can access the only poison weapon in the game, which makes her value higher than other characters against Adel. Adel is only weak to poison, dealing both more damage, and stunning him because it makes him vomit.

It is still only one weapon, so you are better off finding an area with the poison modifier to guarantee a poison weapon that falls into your weapon categories.

Double dodge works great into Adel since he can be very slippery and dash quite far away sometimes, making it pretty useful for closing the gap.

Equipment Loadout

Armaments

Best-in-slot

Alternatives

The only type of weapons we want for this boss deal poison damage. There is only one weapon in the game that always does this: the Serpentbone Blade. The rest of the weapons are generally good weapons, especially if you find them with poison damage on them.

Spells

Best-in-slot

  • Poison Mist
  • Poison Armament
  • Bloodflame Blade

Alternatives

  • Carian Slicer
  • Black Flame Blade
  • Swarm Of Flies
  • Briars Of Punishment

Again, we want poison damage, and the best ways to get that are Poison Mist and Poison Armament, which are usually both on the same Seal. Other good ones are blade covers like Bloodflame Blade or Black Flame Blade because they deal %HP damage to the boss using Black Flame and Bleed.

Talismans

Best-in-slot

  • Warrior Jar Shard
  • Faithful's Canvas Talisman
  • Winged Sword Insignia

Warrior Jar Shard is especially good if you have a poison weapon because you want to spam that weapon skill. Otherwise, Winged Sword Insignia and Faithful's Canvas Talisman get the job done for you.

Alternatives

  • Dragoncrest Shield Talisman
  • Godfrey Icon
  • Erdtree's Favor

Consumables

Best-in-slot

  • Pickled Turtle Neck / Exalted Flesh
  • Greenburst Crystal Tear / Greenspill Crystal Tear
  • Starlight Shards
  • Fetid Pot

Dormant Powers, Passives, and Relics

Dormant Powers

Best-in-slot

  • Improved Sorceries & Incantations
  • Improved Physical Damage Negation
  • FP Restoration upon Successive Attacks
  • Improved Affinity Attack Power
  • All Resistances Up

Alternatives

  • Improved Stamina Recovery
  • Raises attacks of magic, fire, lightning, and holy affinities (8%)
  • Increased Maximum FP

Relics

Best-in-slot

For the best results, buy Duchess’s goblet from the small jar bazaar shop.

Yellow Relics

Green Relics

Weapon Passives

Best-in-slot

  • FP Restoration Upon Attacks (+2)
  • Improved Damage Negation (Physical or Holy preferably 15%)
  • Improved Charged Incantation (+20%)
  • Improved Incantations (+11%)
  • Attacks Inflict Poison (+23)

Alternatives

  • Improved Charged Incantation (+20%)
  • Attacks Inflict Rot (30%)

These alternatives are still great! But the top priorities are the best-in-slot ones.

Game Plan and Pathing

Day 1

You need poison weapons, so look around the map for any ruins with the poison modifier, make your way there while clearing Forts, Cathedrals, and Encampments, so that you are a minimum of level 5 and preferably level 6 once you reach it. After this, we want to go to a mine to upgrade our weapon to epic and clear some Field Bosses so we reach level 8 during day one.  Do not try to kill Elite Field Bosses. They are too tanky at this point, and you will waste too much time on them.

It can also be very useful to move past the central castle to check if Trolls have spawned. If they did, we only want to enter this place around level 11-12.

If you can’t find one of our recommended weapons, try finding one within the weapon categories: Straight Sword, Dagger, Thrusting Sword, Heavy Thrusting Sword, Spear, and Curved Sword.

Day 2

Since we checked the enemies inside the central castle on day 1, we should know by now what the enemies are. As long as they are not Trolls, we can go there straight away, kill all the enemies, and easily reach level 12-13 without killing the top and bottom bosses. Otherwise, wait until you are level 11-12 to go there.

If a shiftin-earth event occurred, go straight away if you want to clear the Crater or Noklateo, and wait till later on the day for the Mountain or Rot Forrest. The latter don’t take as long, meaning you have time for other things during the day.

If a Settlement is spawned, be sure to check it out to see if any good loot can be found there. If you still require some levels or want a better weapon, try to kill some Elite Field Bosses. By this point, they shouldn’t be too hard.

Day 3

Adel will always charge forward once he enters the arena. You can easily get through phase 1 if you have a poison weapon, since you can make him permanently vomit. Otherwise, he has two dangerous attacks: His grab attack, which tends to be an insta-kill if you are below level 13, and his skull smash, which has an AOE dealing a good amount of damage.

Once he hits 50% HP, he will transition into phase 2, which starts with a giant lightning explosion followed by a divebomb, which deals massive AOE damage. You can roll both, but I recommend just running far enough away to dodge both.

He can now do the divebomb attack when he feels like it as well. During phase 2, his skull smashes gain lightning aftershocks, which deal a lot of damage, and he can also follow up on his grab attack with another grab.

For the rest, he is very similar to phase 1, apart from the fact that he will not vomit anymore.

Additional Tips

  • Duchess can dodge twice in a row with her passive; this can be very useful in dodging Adel’s Grab.
  • Be sure to use consumables on every boss since they are everywhere and found easily.
  • Your Ultimate gives everybody Stealth no matter where they are, which means it can be great for reviving teammates as well.
  • Restage is best used when you stagger this boss. You can also use it during his vomit since he is very exposed then.
