Last night when doing HC Chimaeron I discovered something quite neat. If you use Hand of Protection on the tank before a massacre, he won't take any massacre damage. It really helped us out, as it enabled us to enter feud phases with a full health tank. The tank can also take the first hit during feud while still having the bubble, thus always mitigating that hit aswell (provided he taunts).
Got me wondering why I've never read about it before in any guide or on any forum, as it's another really nice trick to make those feuds a bit easier. It might be just a bug, as massacre deals magic damage, and HoP shouldn't block magic damage.
Anyone else who has been doing this?
