Unleashed coming to GMS starting June 19th!

how in the world do they expect to kill bosses with only 5m damage aside from the few that get fafnir early

Having a Fafnir weapon will not help with anything. We will not get CMS system where damage cap is connected to weapons, nor will we get KMS additional options, so Fafnir weps will not get that extra ignore and boss damage. The few extra attack they have over Empress and Loveless weapons are not going to do diddly squat.

If I recall correctly [MENTION=10355]Girasol[/MENTION]; told us we won't get additional options right? So what are we getting?

Nothing to directly replace that system, as far as we know. No information of such a system has been released, and I doubt it will come with this patch.
The damage cap is still being raised though.
