I'd say both humanoids and giants.I started updating the Dodkong as discussed, but I'm not finished yet and my lunch break is over! However, I did want to note that I am adding a "raise dead" ability to the Crown of Obadai as that is one ability I actually found mentioned in my research, My question for you (@Cleon & @Casimir Liber) is: should this ability just be able to raise dead giants or humanoids too, or any creature? Any thoughts?
Re range of detect life. So shall we say 300 feet?
Detect Life. The cairn wight can sense the aura of creatures within 300 feet that aren't constructs or undead. It knows the general direction only. This gives the sensed creatures disadvantage on Stealth rolls.
