Introduction:
If you are a player level 250+ and have access to The Cobra Bastion, you should know that there is a Flask with Snake Poison 
that can be found in their kitchen and if you use it in the local cauldron to poisoning their soup, the creatures of the bastion will spawn with –2000 points of live and weaker for 30 minutes, making it easier to defeat.
Requirement:
– level 250+
– Concluded The Order of Cobra Quest.
Obtaining:
Since some people want to dominate the respawn and it just spawn once a day at the third floor (#3), it is a little difficult to get, but it worth trying!
You must have in mind that it will be empty and it will be called “empty ritual flask“ and as said it will respawn once a day at server save. It cannot be obtained in the market, only a player can sell it and its price is not defined. Once you get it, go to a place where you can find a Cobra 
, kill it and use the empty flask on its body to take the poison, turning it into a Flask with Snake Poison.
