Should be noted that this ingredient is required for most of the vigor/sign potions: Tawny Owl, Stammalford's Philter, and Lapwing.

If your playstyle is mage-like or otherwise depndens on vigor, spend some time farming the embryos off ch 1 Endrega mobs (I've seen them drop off every type of Entegra in the game, not just workers) BEFORE you destroy even one of the coocoons. There is a *marked* drop in the spawn rate of these mobs once you start destroying any of the nests, whether or not you have the quest for nest destruction. Wacking a couple of the nests a bit to bring mobs to their defense works, but leave the nests alive till you're satisfied with your collection.

The wraiths you face in ch 1 do not respawn, so your collection of essence of death is pretty finite at that time. You *need* the Queen's pharamones for a quest later. The Karyan parts apply to other things you may or may not need, the arachas eyes are for the Melete's heart quest (and/or they are a very expensive alchemy purchase from the elf in the forest). In short, I think this is the rarest alchemy category in Witcher 2.
