Kirah is able to make the melee proc poisons now, up to about level 55 or so. Hopefully I'll get up to 65-70 in the next few days.
I've done a little more research on exactly what I need to make them.
Spiders Bite ##: DD proc that scales to level. They are made from the various types of Nigriventer venom found on mobs around Norrath. I can't use these to skill up, however I don't have a problem making them and stashing them in the guild bank for general use. They can be a significant contributor to DPS in certain situations. They can also be resisted a lot depending on the level of the mob.
Scorpion's Agony ##: DD + Anger proc that would be best suited to toons in a tanking role. These are made with various types of "Gormar Venom".
To determine what level of poison the ingredients make, just consult the 'Required Level' on the venom. For example, "
Concentrated Grade AA Nigriventer Venom" has a 'Required Level' of 60, and would be used to make "
Spiders Bite X", which has a required level of 60.
There are many other poisons that can be made using the various other venom types. It's beyond the scope of this post to list them all, but suffice to say some of them can be situationally useful (i.e. proc a slow, a snare, a debuff, etc...). The same thing applies with these. The Required Level of the venom determines the required level of the poision, and thus will determine how effective it will be. If anyone has any interest in these, feel free to supply the venom and I'll be happy to make them for you. I'm not stockpiling venoms other than the two I mentioned above, and those will be converted to poisons fairly regularly.
If you want me to convert the the venoms to poisons for a specific toon (an alt or whatever), I'd suggest handing the kirah the poisons directly. I'm not going to keep track of who deposited what in the guild bank. If I see venoms in the guild bank, the resulting potions will go back to the guild bank for first come first serve consumption.
