Editing LeviathanTempest:ChapterFour (section)

==== Adaptations ====
Comparatively, there are paths that a Leviathan can avoid taking in their exploration of a Channel, certain modes of thought or varieties of adaptation that only become apparent to those that search for them specifically. The Tribe refers to these elaborations of the Vestige as its Adaptations. They are of somewhat greater social and mental importance to a Leviathan than the Channels themselves, as they are improvements that are deliberately sought – by internalizing these traits, a Leviathan is making a claim as to what he believes his (or even ''the'') ideal form ought to be. While the marking of a Progenitor's bloodline causes a Strain to favor certain Vestiges, it is the will of the Leviathan that guides him to more readily undertake a group of Adaptations.

Mechanically, an Adaptation is like a Merit – a unique feature purchased separately from other traits. Adaptations are tied to Vestiges or Channels, and provide to the linked powers either additional benefits, new avenues of use, or reduced limitations. Adaptations always have a physical marker that makes them readily apparent to observers – a true scholar of the Tribe might even be able to identify a Leviathan's School and mastered Channels from observing his Adaptations.  

===== Sidebar Page: Attribute-Boosting Channels =====
A number of Channels provide the Leviathan with bonuses to a specific Attribute. These follow a general template, depending on whether the Attribute is from the Power, Finesse, or Resistance group. To save on space, the basic templates are below, with specific details listed under the individual Channel.

====== Power Attribute Boosting Ancestral Channel ======
* “Depth 0”: Birthright, as appropriate
* “Depth 1”: 9-Again on rolls with (Attribute)
* “Depth 2”: As above, and +1 to the Attribute
* “Depth 3”: As above, but now 8-Again on rolls, and when the Leviathan spends Willpower on an active (Attribute)-based roll, they gain +5 dice instead of +3.
* “Depth 4”: As above, but now +2 to the Attribute
* “Depth 5”: As above, and when acting unopposed or unresisted or by spending a point of Ichor, the Leviathan may perform (Attribute) actions as rote actions.
* “Depth 6”: As above, but now +3 to the Attribute; (unique power)

====== Finesse Attribute Boosting Ancestral Channel ======
* “Depth 0”: Birthright, as appropriate
* “Depth 1”: (Unique Power)
* “Depth 2”: As above, and 9-Again on rolls with (Attribute).  
* “Depth 3”: As above, and +1 to the Attribute, and when the Leviathan spends Willpower on an active (Attribute)-based roll, they gain +5 dice instead of +3.
* “Depth 4”: As above, but now 8-Again; (Unique Power)
* “Depth 5”: As above, but now +2 to the Attribute.
* “Depth 6”: As above; (unique power)

====== Resistance Attribute Boosting Ancestral Channel ======
* “Depth 0”: Birthright, as appropriate
* “Depth 1”: When the Leviathan is using (Attribute) to resist a rolled action, his attacker does not benefit from 10-Again. 9-Again or 8-Again will "degrade" one step.
* “Depth 2”: As above, but now an attacker with no re-rolls negates one success for each "1" rolled. 9-Again will "degrade" to no reroll, while 8-Again will "degrade" to 10-again.
* “Depth 3”: As above, and +1 to (Attribute) and the Leviathan boosts his resistance by 4, not 2, when spending Willpower to increase the Attribute.
* “Depth 4”: 8-Again will "degrade" to no re-roll.
* “Depth 5”: As above, but now +2 to (Attribute); (unique power)
* “Depth 6”: As above, attackers benefit from no re-rolls under any circumstances; (unique power)

At Depths 2 and 4, the Leviathan also gains the 9-again and 8-again properties for uncontested rolls incorporating the Attribute. At Depth 3, he gains +5 dice instead of +3 when expending Willpower to improve a roll incorporating the Attribute.

===== Sidebar: Stacking Multiple Bonuses =====

One thing Leviathans are really good at is enhancing their own abilities through Transformations. It is quite plausible that a Leviathan will have multiple Channels enhancing a trait. When this happens Channels stack in the following way: 

When the Leviathan benefits to a change in the dice roll (such as 9again, 8again, Rote Actions, or automatic Successes), choose one mechanic from each of the Channels.

The Leviathan may only benefit from a single passive increase to any one Attribute, Skill, Armour, or natural weapon. A passive increase is one which occurs automatically with Transformation, such as any of the Attribute boosting Ancestral Channels or Channels that add Sheol to a Skill. If more than one passive Benefit applies use the greatest benefit and ignore all others. For the purposes of this rule a "single benefit" consists of one Channel and any relevant Adaptations of that Channel. 

Benefits to Attributes, Skills, Armour and natural weaponry that require an expenditure of Willpower or Ichor to activate stack with passive benefits. However, only one such benefit may be active for a particular Attribute, Skill, Armour, or weapon at any one time. 

Channels that directly benefit a derived trait such as Speed, Health, or Defence always stack. 

Size from a Channel stacks with the natural increase of Size from Transformation, but two Size boosts from two separate Channels may never be stacked.  

Channels that provide unique effects without modifying the dice roll or the Leviathans traits, such as turning the Leviathan invisible or poisoning anyone struck by a natural weapon, are not covered by the above rules. Generally they can be assumed to stack with anything.
