Q1: On my current run, i've had 6 heralds pop up until now, after terrorizing 2 acts. Nothing notable drop yet - do you guys usually continue terrorizing the rest of the acts and as the herald number goes up, does the drop rate of a Sundercharm exponetially grow? Is it known by now how that mechanic works or is it purely RNG?
Q2: My unserstanding was, that every boss can drop only 1 of 5 statues - eg. Duriel only drops Korlic. Today Duriel dropped Talic (a1 Statue). Has that happened to anyone? Bug or feature?
1) once Herald of Terror aka Herald Tier 5, odds at Sunders dont get better. It can be Herald number 5 or 20, same odds.
Gets only better from 1 to 5.
2) every boss can drop every statue.
