Can a Mercurian attack undead without taking dissonance?
Not if they’re human undead. Mercurians cannot attack humans in any form: alive, undead, ghosts, dreamshades, blessed or damned souls, or Saints. However, Mercurians can attack demons, animals (although they risk Jordi’s wrath), plants (although they risk Novalis’s wrath), inanimate objects, and ethereals. As a side note, whether or not a Mercurian can attack an angel – including himself – is not defined yet in canon; this decision is currently up to the GM. Yes, attunements may get around this restriction; a Mercurian of Judgment would be able to harm a suitably guilty undead, for instance. (However, just being undead may not be enough of a crime to allow this!
