What determines the mastermind fight difficulty level?

I am currently thinking about giving a third shot at killing this annoying boss. It's been difficult for me so I wanted this time to be as easy as possible.

I had a person in global chat tell me that it is the ranks of the syndicate leaders that determine the fight's level, but then this this on the other hand gives contradicting information.

Which one is right? I'd like to know if I need to have backup in case I can't kill her for the third time.

I have all safehouse leaders currently at 1 star rank, but I have cleared tier 14 maps...

Same as incursion, they take the average level of the zones in which you gathered intel, add a few points, and then cap it at the highest level zone used for gathering intel.

Current safe house leaders have absolutely nothing to do with it.

I have gathered my intel farming Harbor Bridge. I guess I'm gonna be fine in that case.

Edit. Nope. fight was level 81. died 6 times.

You probably had some of the encounters in maps, before switching to Harbor Bridge.

The level of the fight seems to determine the speed of the totem's attacks and her movement speed. also it adds that f*ing explosive skeletons attack, which I don't remember at all in my first fight (~72).

At level 80+ it's pretty ridiculous.

You're right. I think I might have done a high tier map or two in the middle of it all. I thought it would be insignificant but I guess not.

It's pretty obvious that the highest level zone you've done while doing syndicate encounters is what Mastermind zone is going to be, if you've done a single t16 map and completed syndicate encounter there, Mastermind, as well as that safehouse is going to be level 83.

Yeah, it is not avg as some believe it's highest level map.

Not that obvious to me but whatever.

Yea this seems more correct than average level. I did just one T15 map with a syndicate and did the rest of them at some Act 10 place and it was still a level 83 zone

When you think about it it's no wonder only 3% of betrayal encounters have ever killed her

I can confirm now that it is indeed true. I have now painfully farmed all the intelligence to fight the mastermind in Harbor Bridge and as a result, the monster level was 68 this time. The fight was easy. (Even though I still got instagibbed at one point and I don't have a clue how it happened. Maybe those crawling suicide bombers? those still hurt a lot...)
