The main item you need for this setup is Energy Drink. Then, you need either a Nazar with Curse of Toxicity, or Necklace if another member has a Contagious Curse of Toxicity.
Secondary items include Compass, Glasses, Goggles and Mystery Meat. In addition, Exhausting Curse can also be used.
The main objective is to get more animals, as well as finishing quests if you have Compass. The steps are as follows:
Use Glasses, Goggles and Mystery Meats to raise your rescue cooldown high. Remember to use Glasses before Goggles, since Goggles can copy the ‘guarantee a pair’ effect from Glasses. Use Energy Drink to increase your rescue cooldown by 6 hours, and to instantly rescue. You can also remove an Exhausting Curse to increase your rescue cooldown high, if you decide to do the setup with Contagious Curse of Toxicity.
Then, use Compass to shorten your quest dramatically due to the high rescue cooldown. The higher it is, the better Compass will be.
There are two ways to get a Weakened Curse of Toxicity. If you have a Curse of Toxicity before beginning this setup, you can use a Nazar to weaken it. If someone has a Contagious Curse of Toxicity, you can equip Necklace and trade with them.
You probably have a ridiculously high rescue cooldown by now. You can either use a Compass or an Energy Drink to remove that cooldown entirely, due to Weakened Curse of Toxicity inverting the effect.
You may get a curse from quests, which will override your current Curse of Toxicity. This would mean you’d have no way of inverting the high rescue cooldown.
Therefore, it is recommended to do Peaceful Quest, use a Safety Pin, and use Lazy as the quest modifier. If you want to take no risks, you can either not use Compass, or just do the setup with Contagious Curse of Toxicity.
