Boss defense/resist

[Addah]

My question is what amount of defense do Dreamlands, Lichking, ubers/omega, and stuff like that have?

Also while I'm here what resist % do they have to each element?

Do these things scale with game difficulty from more players?

I would just google it but I feel since overall difficulty is higher here that the amount of defense will be more on enemies, and my main concern is the custom content.

I'm looking for specifics to make sure my characters always have 95% chance to hit on every enemy, to calculate my magic penetration, then put the rest into my health.

The answers would be here if the post was "complete".....

The thing about most of these endgame bosses isn't their defense, but they have a built in chance to dodge all abilities, like amazon passives if you will. The amount varies, some bosses have 25% and some scale all the way up to 75%. I am the only person with this information, maybe I will find a way to get it where it is easy to read one day but it is actually a lot of work and isn't high priority. Regardless, even if your attack rating says 95% chance to hit it isn't taking into account the chance to dodge.
