So probably jumping the gun here, but what happens when you are using danarti to attack (with a hit modifier) and your opponent triggers two blight tokens?
Technically you still roll 3 dice, and the rule for canceling is for no dice to roll :
10.3 of rules
If a game effect removes dice from an attack such that
there are no dice to roll, the attack is canceled.
By RAW I would say attack is not canceled, but in a real game I'd probably cancel it. Wanted to see the forums thoughts.
Note: I am assuming the darnati ability forces you to lose 1 die per attack (I know this is still debated).
