If you're referring to the highlighted section in your image, I'm not using that for my calculations. Technically it's doable, but it's inordinately complicated since the PAM build is already using the bonus action for the PAM attack. You'd have to determine under which circumstances you'd replace a 1d4 attack with a 1d10 attack to make use of that.
I had it in earlier versions of my spreadsheet, but took it out in later ones because it was too complicated to deal with for too little benefit.
The damage I'm including is the second component, which requires hitting with a heavy weapon, which PAM requires, so they automatically work together. It only requires that you land at least one hit on your turn with the Attack action, to deal your proficiency bonus in damage.
It doesn't seem very complicated, so I didn't provide any extra details. I'll admit that I assumed people would be familiar with the playtest changes, since I've already gone through a lot of arguments and analysis on this back when it came out (which is like a year ago), and didn't add extra details here. (My posts are long enough already.)
I only went into a single barbarian build because I didn't want to make this overcomplicated (and that was in turn referenced by
@strawbellebelle , so I continued with that in the explicit math explanation). If I want to examine different barbarian builds, I'll do that in the barbarian thread. I just took a modest baseline build to see where different monk builds fell in comparison to an already known quantity.
slover -> sliver?
I can only compare with what we have available. Speculating on what WotC
might add in the future is useless for our purposes of evaluating the current state of the playtest. If some new feat is added or changed (such as what happened with the Epic Boons), then we can go back and redo things from scratch to see where things now fall.
And I happily welcome anyone coming up with a different idea of how things could work, some new combination of feats or abilities. I will happily change my approach if something better comes along. It just tends to not happen, as threads devolve to petty arguments over unrelated matters. (See: Warlord and fighter arguments in the sorcerer thread.)
