Key Guardians

So I’m trying to find a lost sanctuary key guardian and I searched the wiki and went to the places but they weren’t there. When will they respawn and what is the best way to get keys

 

There's not a lot more than what is already on the wiki, just search Time valley and the area around Detlas (ive found some at the netehr portal). Just stay at those areas for a while and kill mobs, you should get a key guardian in way less than an hour.

 

K imma just chill in time valley ty for advice
