Arghhh Basilik salivaFollow

I'm not sure, but maybe we can help at least give some direction. If you know how new/old the alchemy item is maybe you can narrow it down to zones from a certain expansion and then check http://eqbeastiary.allakhazam.com/search.shtml?name=basilisk.

For example, there are DoDH basilisks in Undershore and Stoneroot, DoN basilisks in The Broodlands, and GoD ones in Nedaria's.
