Takeshied Shugenja uses Jade Embrace on Big Bad Berserker. Big Bad Berserker uses Deep Roots. Does he negate the Force Penalty from Jade Embrace?
Tamori Takeshi and Jade Embrace vs Force Penalty Negation
A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
Jade Embrace reduces Force to 0. This is a Force penalty.
Takeshi says that the effects from actions performed by the target will not be negated. Ergo, the Force penalty from Jade Embrace (performed by a personality under the effects of Takeshi's ability) will not be negated.
Deep Roots tries to negate the Force penalty. "Will not be negated" from Takeshi trumps Deep Roots' negation.
The Force penalty stays. Big Bad Berserker is F0.
