The Conduct Energy free action states as a requirement:
Your last action or spell this turn had the acid, cold, electricity, fire, or sonic trait.
The Conducting rune grants a weapon etched with it the Resonant trait, granting access to Conduct Energy.
If I etched that same weapon with, say, a Corrosive rune, would it grant any Strikes made with that weapon the Acid trait?
If so, does that mean that the following sequences of events is legal, RAW?
- First action: Strike (with the acid trait)
- Free action: Conduct Energy
- Second action: Strike (with the Conducting rune now active)
If so, does this mean that the second Strike would deal x[W] + 1d6 acid damage + 1d8 acid damage, where x is the number of weapon damage dice and W the weapon damage die?
tl;dr Does having a Rune with e.g. the Cold trait on a weapon make Strikes with that weapon also inherit said trait?
My gut says yes, as this seems to be the mechanism by which magic weapons grant Strikes the Magical trait:
Ghosts and other incorporeal creatures have a high resistance to physical attacks that aren't magical (attacks that lack the magical trait).
