Why don’t I get a Kanduran Rune after completing all Act I bounties and talking to Tyrael?
Instead he gave me another large Horadric chest (which I already had one of). I googled how to get a horadric cache to get a Kanduran Rune and it said do all Act 1 bounties, then talk to Tyrael. EDIT - worked out that the chest must be the "Horadric cache/2 and when I clicked on the chests got lots of item and gem plans to train crafters, plus some Khanduran runes.
