Gobtruffle should do extra damage per diseased/poisoned enemies.
Today, he’s not.
Here are couple of screen shots from today’s faction assault.
In the first pic we can see Gobtruffle should do 19 damage PLUS one for the diseased enemy.
In the 2nd pic we see the spell in progress … and the dragons are only taking 19 each.
I mentioned this in chat and another player was able to duplicate it.
