Ah, must've forgotten the lock gems on the left side. Those will be added in properly with the next patch!
I'll look into Heartbeat later as well- as a rough guess, it might be related to the Master's Gift multiplying Max HP.
Oh yeah, you're right. I had it in my head that "it multiplies 3 stats" and forgot Block Strength was a stat, sorry.
I'll definitely look at Heartbeat later. It shouldn't be a HUGE deal (the most impact I can see it having is setting up Perilous Punch strats), but I expect it's probably related to the underlying code. Now that my coding skills have improved, I could probably fix it given some time.
