I have seen a lot of people putting the seed for 1688171794 - there is a mansion but you need to go a distance to get there.
If you use seed -6832647006559365268 ... a woodlands mansion will be right at the spawn point... make a stone sword and kill the evoker. Grab the totem it drops and place it in your hand... once you are holding it, find a Vindicator and just wait for him to kill you, you will stay alive and 4 golden hearts will appear over your health to show it has worked. This will be stackable with Feeling Ill.
Hopefully that helps.
