Sevatar

When engaged in a Challenge with a model whose Weapon Skill is 5 or more, Sevatar gains the Instant Death special rule on all attacks made during that Challenge.

Sevatar gains access to the Shadows of Past and Future Psychic Power only and gains no other Disciplines, Psychic Powers or Psychic Weapons.

A Talent for Murder: When a unit made up entirely of models with this special rule attacks during the Fight sub-phase or makes a Shooting Attack against an enemy unit that is Pinned, Falling back or outnumbered by the attacking unit it gets a bonus of +1 to all To Wound or Armour Penetration rolls made during the Shooting Attack or Assult. 

When determining if a unit is outnumbered, models with the Bulky (X) special rules count as a number of models equal to the value included as part of that special rule. Models with the Vehicle Unit Type count as ten models for the purposes of determining if the model is outnumbered by another unit.

Independent Characters can join other units. They cannot, however, join units that contain Vehicles, Dreadnoughts, Automata or any model with the Monstrous sub-type (unless the Independent Character also has that Unit Type or sub-type). They can join other Independent Characters though to form a powerful multicharacter unit.

Joining and Leaving a Unit
An Independent Character can begin the game already with a unit, either by being deployed in unit coherency with it or, if the unit is in Reserve, by you informing your opponent which unit it has joined.

In order to join a unit, an Independent Character simply has to move so that they are within unit coherency distance of a friendly unit at the end of their Movement phase. If the Independent Character is within unit coherency of more than one unit at the end of its Movement phase, the player must declare which unit it is joining. If an Independent Character does not intend to, or cannot, join a unit, it must, where possible, remain outside of unit coherency with that unit at the end of the Movement phase. This is to make clear whether they have joined a unit or not. Note that after an Independent Character joins a unit, that unit can Move no further that Movement phase.
An Independent Character can leave a unit during the Movement phase by moving out of unit coherency with it. They cannot join or leave during any other Phase – once shots are fired or Charges are declared.

An Independent Character cannot leave a unit while either they or the unit are in Reserve, locked in combat, Falling Back or have been Pinned. They cannot join a unit that is in Reserve, locked in combat or Falling Back. If an Independent Character joins a unit, and all other models in that unit are killed, they again become a unit of one model at the start of the following Phase. While an Independent Character is part of a unit, they count as part of the unit for all rules purposes, though they still follow the rules for Characters.

Special Rules
When an Independent Character joins a unit, it might have different special rules from those of the unit. Unless specified in the rule itself (as in the Stubborn special rule), the unit’s special rules are not conferred upon the Independent Character, and the Independent Character’s special rules are not conferred upon the unit. Special rules that are conferred to the unit only apply for as long as the Independent Character is with them.

Independent Characters and Infiltrate
An Independent Character without the Infiltrate special rule cannot join a unit of Infiltrators during deployment, and vice versa.

Independent Characters and Ongoing Effects
Sometimes, a unit that an Independent Character has joined will be the target of a beneficial or harmful effect, such as those bestowed by the Blind special rule, for example. If the Independent Character leaves the unit, both the Independent Character and the unit continue to be affected by the effect, so you’ll need to mark the Independent Character accordingly.

Conversely, if an Independent Character joins a unit after that unit has been the target of an ongoing effect (or joins a unit after they themselves have been the target of an ongoing effect), benefits and penalties from that effect are not shared.

Relentless models can shoot with Heavy or Ordnance weapons, counting as Stationary, even if they moved in the previous Movement phase. They are also allowed to Charge in the same turn they fire Heavy, Ordnance, or Rapid Fire weapons.

All enemy models within 12" of a model with this special rule must reduce their Leadership by the value in brackets after the special rule when taking any Morale checks. Regroup or Pinning tests. For example, a unit with the special rule Fear (2) would reduce the Leadership of all enemy models within 12" by 2
Enemy units that are locked in combat are only affected by this modifier if they are locked in combat with the unit that causes Fear. This modifier is not cumulative, and any given unit can only be affected by a single instance of the Fear special rule at a time.This will always be the highest single modifier among those applicable.

A model that causes Fear is not itself immune to Fear and will still suffer a penalty to its Leadership if within range of an enemy unit that has the Fear special rule.

If a model with this special rule, or attacking with a weapon with this special rule, rolls equal to or higher than the value in brackets when making a To Hit roll as part of a melee attack, that hit is a ‘Precision Strike’. For example, if a model with the Precision Strikes (4+) special rule rolls a 4 or higher when making a To Hit roll, then that attack is a Precision Strike.
Wounds from Precision Strikes are allocated against a model (or models) of the attacking player’s choice in the target unit, as long as that model is engaged in combat with the attacking model’s unit, rather than following the normal rules for Wound allocation.

A model with this special rule may only be included in an army that has the Traitor Allegiance.

When a unit composed entirely of models with the special rule declares a Charge targeting a unit that is Pinned or Falling Back, the Charge roll gains an additional +1 modifier, and if the Charge is succesful then all models in the Charging unit gain +1 Attack for the duration of the turn in which that Charge is made.
