Yesterday I was able to try a strategy I came up (sorry if someone already figured this out and shared), and I could kill 5 ~7 Herald of Terror.
Heralds are carried through Acts, so what I did to save some investment, TZ was Kurast area, which means roughly ~30% of Act 3 (free, no Shard investment necessary). I was lucky enough to had 2 Heralds encounters.
Then I used a Western Worldstone Shard which terrorizes Act 1. I was able to find 2 more Heralds until Cold Plains. In no time I was killing my first Herald of Terror.
In between Act 1 maps, I was trying to clean every other TZ that appeared.
I had very solid drops, as such War Travelers (48% MF
No new sunder whatsoever
BUT I am happy that, right now, I have a more solid strategy to farm those.
Let me know your thoughts, and your strategy.
