Also, you will find that TK will not protect you from damage by the majority of chests indoors. The reason for this is that TK only works if you have line of sight and can click on the chest, and in most cases, you can't simultaneously see the chest and get far enough away to prevent damage if it blows up. That's a major reason why my preferred parties for both the Light (APCS) and Dark (ACSS) Paths include an archer.
