Slannesh lore for WOC

Here is an exhaustive discussion: warhammer-empire.com/theforum/index.php?topic=48475.0

Here is my conclusion (p. 4):

There may be a way to merge all views.

- All Attacks are part of the Attack characteristic (as per BRB p. 48)
- The Attack characteristic cannot normally exceed 10 (as per BRB p. 3).
- However, a random characteristic value can go above 10 (as per FAQ).

If you have a fixed number of Attacks at the start of a round of close combat, this cannot exceed 10. This includes all the Attacks (from whatever source) you actually can count: profile, weapons, active spells, special rules (Frenzy, Bloodgreed...)

Attacks from some special rules like Blood Fury etc. are part of the Attack characteristic, but are not fixed - you do not know at the beginning of a round of close combat how many Attacks that will deliver. Models with such a rule can be said to have a random characteristic value, and thus fall under the FAQ.

This could be just as valid as a total cap on Attacks; and an FAQ seems warranted - but that is unlikely to be forthcoming.

Yep. Same for the Random Movement special rule:

BRB p. 74: Models with the Random Movement special rule do not have a Movement characteristic.

Therefore, it cannot be capped at 10.

And as per FAQ (Official Update Version 1.9 p.14):
Q: Does Birona’s Timewarp affect units with the Random Movement or other movement special rules? (Reference)
A: Yes, however far they can normally move, it will be doubled. For example, a unit with the Random Movement (2D6) special rule rolls a 9. This would then be doubled to 18.

Since we are on the subject:

1. Note that for WS, BS, S & T, the BRB charts simply do not foresee possibility to resolve cases > 10.

2. Even with the cap, a characteristic > 10 is still useful, because there are always hexes or other effects that may lower the value. That said, the BRB does not specify how to calculate the characteristic values. In my view, the easiest and most consistent way would be to add all the boni and mali, and at the end apply the cap, if necessary. I consider this to be a simple calculation, not a sequencing of rules. However, I have noticed others argue that this falls under the Sequencing rule, in which case the player whose turn it is chooses the order of the calculation. That does not change anything in the turn of the controlling player, but the opposing player could first add up all the boni, apply the cap if > 10, and then subtract the mali, leading to a value < 10.
