I'm trying to calculate the required DPS on bosses based on the boss' HP. Now obviously this scales dependant on the size of the raids.

For example The Butcher on Heroic mode apparently has 66,080,000 HP according to wowhead. The issue here is that it doesn't state what raid size he has this health at.

It would be nice to understand the algorithm behind the scaling in order to calculate what health the boss would have at any given raid size.

  • That's where I got the 66 million from. that doesn't state at what raid size he has 66 million at. Jan 29, 2015 at 11:02

    Good question, but appears to be essentially a duplicate of gaming.stackexchange.com/questions/196747/…

  • Very Interesting question but far too broad to answer. The bosses HP doesn't just go up by x% for every additional player. It's calculated individually for every boss depending on the bosses mechanics.

  • @Lin Indeed it may be similar, but that question hasn't got an answer. Jan 29, 2015 at 12:48

    I can understand closing it as a duplicate, but why is this being closed as too broad? It's definitely answerable by a single, reasonably-small answer. "It's too hard for me to figure out" does not make it too broad. Jan 29, 2015 at 18:08

This is not an exact figure, but working it out based on the figure of a 25 man raid he has 111,700,000 health and 134,300,000 in 30 man raid.

(111.7 / 25 = 4.468 * 30 = 134.04)

That's the closest I can get it.

Giving wowhead gives us the health for a 15 man raid we can then use this data to adjust the formula accordingly.

(h / 15 = 4.403r * n) = scaled_health
