SLAYER Missions Guide

Missions are the repeatable mid-game loop in SLAYER by kriel once you finish onboarding at Frozen Shroud. The Familiar menu (M) lists combat and investigation jobs that pay Yen and EXP, sometimes with weather or difficulty modifiers that raise payouts and enemy pressure. Longer sessions can push into raid-style content such as Infinity Castle. This guide explains how to pick missions, when modifiers are worth it, and how mission farming ties to Yen Farm, Hideout Training, and Progression.

Public testing still reshapes objectives and map geometry. Prefer the live Familiar text when a name or modifier differs from this page, and skim Updates after patches.

When to start mission grinding

1. Finish the tutorial and redeem Codes.
2. Learn dash, parry, and Breathing refill from Controls.
3. Buy a cheap Parry Training set from Hideout Training.
4. Slayers: clear Final Selection and finish Nichirin Forging so forms work.
5. Then treat missions as your main Yen/EXP printer between hideout drills.

Jumping into high modifiers with a wooden blade and zero Cap training is how public-test accounts soft-reset themselves.

How to open and clear missions

1. Press M for Familiar.
2. Open the missions or activity panel shown in your build.
3. Read the objective, suggested pressure, and any active modifier tags.
4. Solo queue or party with players who finish objectives.
5. Complete the live counter (kills, investigations, escorts, or survival clocks).
6. Return to hub, bank Yen into training or forms, then requeue.

If the lobby wipes repeatedly, drop the modifier tier or retrain Parry before blaming the mission type.

Named mission themes (community-documented)

Public-test coverage and longplay chapters describe recurring mission fantasies such as:

Theme	What you generally do	Good for
Village Purge	Clear demon pressure around a settlement	Steady combat Yen
Hunt the Kizuki	Focus higher-value demon targets	EXP spikes when ready
Strange Disappearance	Investigation / search objectives	Mixed pace sessions
Lost Traveler	Escort or recovery style tasks	Party coordination practice

Exact names, unlock order, and rewards shift. Use the table as a theme map, then follow the Familiar card in your session.

Mission modifiers

Modifiers layer extra risk for better payouts. Community reports call out effects such as:

• Storm or fog — vision and positioning pressure
• Enemy damage up (for example +25%) — punishes missed parries
• Other seasonal tags tied to event titles like [2X EXP]

Take modifiers when:

• Your Parry timing from Controls is stable
• You already redeemed codes so deaths are not economy disasters
• You are not mid-gourd soft lock on Breathing Level

Skip modifiers when you are learning a new Breathing Style or Blood Demon Art from the Tier List.

Infinity Castle (longer grind)

Creator longplays of Place 134190081223854 show Infinity Castle as a longer dungeon-style loop with keys, bosses, and extended combat chapters after basic missions. Treat it as a post-Nichirin activity:

• Bring a forged blade and unlocked forms
• Stock patience for multi-phase fights
• Expect public-test tuning on boss telegraphs
• Bank Yen afterward into Hideout Training or form nodes instead of impulse cosmetics

Do not confuse Infinity Castle routing with Project Slayers / Slayers 2 dungeon guides — different games.

Mission farming loop that compounds

1. Redeem codes (Codes).
2. Set a Yen budget (Yen Farm).
3. Run two to three missions at a modifier you can clear cleanly.
4. Spend into Parry / Breathing Cap / gourd breaks.
5. If Slayer forms feel weak, confirm Nichirin equip before buying more nodes.
6. During [2X EXP] titles, bias toward mission volume over idle hub standing (Updates).

Party tips

• Share the objective; do not split into unfinished void map corners.
• Call grabs — letter-escape prompts still end runs.
• Let the weakest player set modifier tier.
• After wipes, retrain for five minutes instead of instant requeue pride.

Missions turn SLAYER from a tutorial combat demo into a session loop. Clear clean objectives, respect modifiers, and spend the payouts on the next real gate — not on wandering the unfinished world for loot that is not there yet.
