Shadow

A folio of the realm

Shadow

Shadow in Britannia is the stealth-hardening Ninjitsu form — a Ninjitsu self-buff that makes the Ninja substantially harder to reveal while hidden. When a hidden Ninja takes damage from an AOE spell, gets pinged by a Tracking check, or is hit by a Detect Hidden reveal, the engine rolls a "stay hidden" check that compares the attacker's reveal mechanic against the Ninja's hide-resistance. The Shadow form boosts that resistance significantly — a Ninja in Shadow form survives reveal attempts that would unhide a non-Shadow Ninja.

The exact bonus scales with the Ninja's Ninjitsu and Stealth skills — at GM in both, the Shadow form's hide-resistance is at its peak. The form is the canonical "stay hidden longer" mechanic for the stealth-tree archetype, layered on top of the basic Hiding skill and the Smoke Bomb emergency-vanish consumable.

Mechanics

Attribute Value
Type Self-buff form (Ninjitsu)
Cast prerequisites Ninjitsu ≥ ~50 to enter Shadow form
Mana cost Modest one-time cost on form-shift
Stamina cost None
Duration Until manually exited or until form-shift to another Ninjitsu form
Visual Ninja sprite slightly darkened / smoky (the in-game form indicator)
Stack with Hiding Yes — Hiding gives the base hide; Shadow boosts the resist
Stack with Stealth Yes — Stealth lets the Ninja move while hidden

The form is persistent — once entered, the Ninja remains in Shadow form across many actions, only exiting on explicit form-shift, character death, or logout. This is the canonical "default Ninja stance" for stealth-builds.

What Shadow form actually resists

Reveal mechanic Shadow form effect
Damage taken while hidden (e.g., AOE spell splash) Significantly harder to be revealed
Tracking skill ping Reduced effective range
Detect Hidden skill Higher detection threshold required
Reveal spell (Magery) Targeted reveal still works (Shadow doesn't block direct reveal)
Caster of a paralyze field stepping past Still reveals (no protection from passive proximity reveals)

Shadow's protection is strongest against passive/area reveal mechanics. Targeted Reveal spells from a Magery caster who has line-of-sight to the Ninja still work normally — Shadow does not make the Ninja immune to direct attention, only resistant to incidental revelation.

How Shadow stacks with Hiding and Stealth

The canonical "stealth tree" build is 120 Hiding + 120 Stealth + 120 Ninjitsu plus partner combat skills:

Skill Function Shadow form effect
Hiding The base "go hidden" skill Higher Hiding = better Shadow base resist
Stealth Move while hidden Shadow form does not block stealth movement
Ninjitsu Gates Shadow form access + Smoke Bomb Higher Ninjitsu = stronger Shadow form bonus

A non-Shadow Ninja with 120 Hiding + 120 Stealth is hard to reveal already; Shadow form is the add-on that makes a hardened Ninja almost impossible to ping with passive mechanics.

Other Ninjitsu forms (Shadow is one of several)

The Ninjitsu skill provides multiple forms as self-buffs. The canonical roster:

Form Effect
Shadow Hardens hide / reveal resistance
Wraith Form (technically Necromancy) Drains stamina from victims into mana
Animal Form (Cat / Dog / Squirrel / etc.) Disguise as an animal — invisible to most aggression
Vampiric Embrace (technically Necromancy) Heal from damage dealt
Lich Form (Necromancy) Mana regen + damage type to Cold

The forms mutually exclusive — a Ninja can only be in one form at a time, and switching costs the form-shift mana. Shadow is the stealth-flavored form; Animal Form is the disguise-flavored form; Wraith / Vampiric / Lich are Necro-tagged forms with different combat effects.

Shadow form in builds

Build Shadow form role
Pure Ninja (Ninjitsu + Hiding + Stealth + Magery) Default form — entered immediately at character spawn
Sampire Rarely Shadow — uses Vampiric Embrace for combat sustain
Mage / Ninja hybrid Shadow when hiding to mass-cast offensive spells
Tamer / Ninja Shadow during pet-engagement to stay hidden behind the pet

The Pure Ninja archetype is the canonical Shadow user — it's the default stealth-build form, used in PvP and PvE alike for any encounter where staying hidden longer is the strategic priority.

Shadow form vs. Smoke Bomb

Mechanic Shadow Form Smoke Bomb
Triggers what Persistent self-buff (form) One-time hide
Use case Out-of-combat stealth + reveal-resistance Emergency vanish during combat
Cooldown None (until form-shift) ~6 seconds between uses
Mana cost Modest one-time on entry None
Stack with each other Yes — Shadow form + Smoke Bomb compound the hide-resistance

A canonical Ninja routine: enter Shadow form at character spawn, then use Smoke Bomb for emergency vanishes during combat. The two don't conflict — Smoke Bomb's instant-hide carries the Shadow form's reveal-resistance bonus.

When NOT to use Shadow form

Situation Reason
Combat with no stealth Form-shift mana is wasted if you're not hiding
Solo PvE bosses Boss won't reveal you; the form's protection doesn't apply
Need Vampiric Embrace heal Sampires switch out of Shadow into Vampiric Embrace mid-fight

In standalone melee combat with no stealth element, Shadow form provides no benefit — just the mana spend.
