Tainted Meat And Tainted Bait Both Count, So You Can Use
Raw Meat Or Cooked Meat
+ Devil's Trumpet (Purple Plant)
This Makes A Throwable Bait, That Kills Wolves When They Eat It.
--------------------------------
As Soon As They Start Wobbling (Before They Fall Down) You Can Occasionally Walk Up To Them And Pick Up The Bait Again, And Reuse It!
This Achievement Is Cumulative (You Can Do This Over Multiple Playthroughs)
--------------------------------
Good Luck!
