Updated to the new stuff.
-Your inventory and stash is split into ISO and Cats. For cat inventory it groups things together, so it just has x2, x3.... for multiples.
-When leveling up a hero, you can click on a "rank up" tab and see what cats it takes to level them up, and it shows what you have in your inventory already, so you can plan a little easier. I know this is in the "kabam cheatsheet" page but I forget some of them.
-Act 4, map 1 has 4 paths, with at least two of them taking 28 nodes to clear. At x3 that is 84 energy. If you go the wrong route you could make it a 36 node path.
-The end boss (the good Dr.) has a local 200x buff, and the Black Panther sitting in front of him has a 100x buff.
-Recommended team is 12500ish I think.
-100% of map 1 gives you a stone thing that sounds like it lets you give x5 to a 3* hero signature ability. So a partial dupe of them I guess. I assume somewhere along the quest we can get 4* version of these.
There is a welcome email that says something along the lines of 5* heroes not being immediatly playable when you get them. Something about a 2 week waiting period for them to figure something out so that the first person who gets one doesn't dominate, blah blah blah. they said a 4* 5/50 would be roughly equal to a 5* 2/35. Good thing we all have 4* that are rank 5, ...oh wait
I am sure someone on MXPX has already finished act 4 by now, and has a fully duped team of 5* in the waiting.
