Hi.
Take this example:
Mik kneels 4 influence and plays Blood Magic: Any phase: kneel X influence to choose a character without attachments. Until the end of the phase, that character gets -X STR and is killed if its STR is 0.
Seb plays Injurious Poison: Response: copy the effects of an event card or character ability just triggered (without paying any cost).
My question is: what can Injurious Poison do? Burn a character with 4 STR (because Mik knelt 4 influence) or burn a character with 0 STR (because of the letter X in the event).
About the "letter X", I've found this in the rules:
(3.1) The Letter X
Unless specified by a preceding card, card
effect, or granted player choice, the letter "X"
is always equal to 0. Further, any card without
a cost of the specified type is assumed to have
a cost of 0 for purposes of determining how
that card interacts with triggered effects that
need to count its cost.
and
(3.11) Definition of Variables
[…]
Triggered Effects and Passive Abilities define
or count their variables once (when the effect
is initiated), and the variable is then constant
throughout the duration of the effect.
When an effect checks a variable but there is
no number present or has no quality capable
of being checked (STR, power, cost, etc.) the
variable is counted as 0.
This, tough, is not sufficient for me to decide what happens in this case. Is Blood Magic considered a "preceding effect", so the letter X has a constant value throughout the resolution of Injurious Poison too?
Thanks.
