DR + Orr?
Yeah the DR seems to kick in on killing a bunch of dudes of a general enemy type rather than the specific enemy type… There’s actually quite a few undead variants in the Orr Zones, yet killing any combination of them up to a certain point kicks in the DR.
Going from Melchor’s leap to the southern tip of cursed shore I have never gotten more than 8 enemy types on the daily kill variety
I zoned into Orr last night and killed 5 mobs, all of which dropped porous bones. Figured, well try some more in a different part of Orr. Same thing happened there too. Think I ended up with around 30 for those porous bones before I decided to try to look for a dungeon group. At least one that doesn’t ragequit in the middle..
