As a Slayer your Crow will bring you different missions to complete. After you finish these missions, you can earn Experience and Yen. You have varying time amounts to complete each mission depending on which one it is.
Rescue Mission[]
You will have to run to a Slayer NPC and pick him up using V, if you press B on accident and execute him you will fail the mission. After you pick him up you will have to run to an inn. There will be a higher demon with a random Blood Art guarding the Slayer NPC. After you complete this quest you will receive 100 Yen, and 350 XP (1750 XP since Update 3.25, 2000 XP as of as on a unknown update.). You have 15 minutes to do this quest.
Delivery Mission[]
Deliver a Package to the Merchant. Rewards Around 500 - 800 Yen. (You stop getting this mission after level 15.)
Hunting Mission[]
Level 14 and below: Hunt down 5 Demons within 15 minutes. Gives around 150 Experience (750 XP since Update 3.25).
Level 15 and above: Hunt down 12 Demons within 20 minutes. Gives around 400 Experience (2000 XP since Update 3.25).
Kill The Green Demon[]
Fight the Green Demon boss. If you defeat him he will drop a Green Horn, which can be used to craft the Crystal Key.
He drops around 200 XP but if you have the quest he will give you 500 XP (1500 XP since Update 3.25)
Save The Village[]
Demons will be spawned near a village and you will have to kill them all within 20 minutes. 4 demons will spawn and at least 2 of them will have Blood Arts. You can get this quest while the sun is out so when the demons spawn in they will all die and you will still get the rewards. Rewards Around 600 Yen and around 300 Experience (1500 XP since Update 3.25).
Notes:
- Slayer missions can't start in private servers.
- if you die, reset or leave the mission will disappear.
- during the rescue mission, if the Demon Slayer NPC is killed, the mission will disappear.
- and if someone delivers the Demon Slayer NPC that's not the mission owner, it will still complete the mission and gives the owner of the mission yen and XP, ONLY if the second part of the quest is triggered.
- if the Demon Slayer NPC wakes up, the mission is now bugged and can't be completed, and you can't knock them down, they have Infinite health.
- Hunt demons quest is the best for leveling up.
- kamakura Village, is the best place for grinding Slayer quests, due to how easily you can go between snow and coast areas.
- You can still start Slayer missions even while being a Hybrid.
