So here is the ability flow for Malice:
Ability:
Ability targets a single ship withing 8000 range
1st Buff:
Buff Targets 8/16/24 ships within 3000 range of the original target
2nd Buff:
Damage is recorded on the 8/16/24 ships for 10 seconds
30% of the recorded damage will be propagated
Weapon damage is propagated at buff finish (10 seconds) to the affected ships only (original 8/16/24) that are in 5000 range of the affected ship.
So for the best affect it's probably good to FF on an affected ship to make sure the 30% damage is as high as possible.
