@FatsharkLev Thank you for the reply.
That’s unfortunate to say the least.
It feels counter-intuitive that they don’t even benefit from map completion modifiers.
Although at least armed with this information we can pick the safest path knowing only 1/4 of the party is benefiting from the buff.
So that Khorne influenced +specials that rewards 4 stamina is certainly worth skipping considering you’ve got a 90% chance to end up with a true solo experience and 3 dead bots. That’s assuming you don’t get disabled and the bots just jump up and down in warpfire while you slowly bleed out.
EDIT:
I think there was a misunderstanding.
Some testing in-game indicates at the very least that bots benefit from the +20% health map modifier.
These seem to be global modifiers as even players that join late benefit from them.
Sorry if mentioning boons caused any confusion.
I’ve not tested if they benefit from miracles although I think from a post above, they do not (but imo they should!).
