Hi folks,
if I remember correctly, you can only inflict (most) conditions like poison, stun et.c if you deal at least 1 D after dice are rolled/rerolled. Meaning that in the case you roll 3 D vs 3 S, you could not use 1 Surge to gain 2 D to then use an additional Surge to inflict a condition.
In that case, the same should apply for using surges to add pierce in order to being able to then inflict a condition.
But what about the weapon Poisoned Blowgun? In this case, the weapon has pierce 1 as a passive ability. Will this instance of pierce be calculated during the rolling dice section, allowing you to inflict poison during the surge step if you roll 2 D vs 2 S?
