So about the currently ongoing campaign "PLUS".
Stuff already present in the non plus:
Each statue killed has a chance (100%?) to drop a rusted card premidboss or Black card post midboss.
When this drop happens it's the same for everybody in alliance regardless of position/distance.
New stuff for the plus:
Each statue killed (red eyes NMs too?) have a chance to drop something else instead of a normal card. This can be a Beastmen Medal or a zone-shard (pre midboss) or a kindred medal / zone-void (post midboss).
The zone-shard and zone-void will always be the one of the specific zone, no bodies. It will also be the one for the
job you're currently on.
Also, when this happens (special "plus" bonus replaces default campaign bonus) it's gonna happen for everyone in alliance, but everybody is getting a specific roll.
To better explain, check this flow
1) Statue 1 get. killed. Char1 gets Rusted Card, Char2 gets Rusted Card, Char3 gets Rusted card
2) Statue 2 gets killed. Again Char1 gets Rusted Card, Char2 gets Rusted Card, Char3 gets Rusted card.
3) Statue 3 gets killed, special "Plus" drop happens. Char1 gets a Beastmen Medal, Char2 gets a Hedashard: BRD (he's on BRD) and Char3 gets a Headshard: DNC (he's on DNC)
So again, tl;dr, when a "plus" bonus drops from a statue, it's gonna drop for everyone in alliance, but everybody is gonna get a different item out of it.
