Ok, Ive hunted the internet for the last few days and all I can find is basically 'A warlock bond is a warlock bond' What is a warlock bond for? Is it worth wasting my time on one let alone any motes of light on legendary ones from the speaker? If its purely decoration then why not make them cheap and easy to get. Also, can they be powered/leveled up or upgraded? Ive got one and it looks like those cheap plastic glowing necklace things you can buy from a cheap shop.
