Apologies for something of a text dump. Much of the information around is incorrect so I thought it would be useful to record what the in-game descriptions say. Some runed skills are missing. This is because if you haven't unlocked the skill you can't read its runes. This is a list of all abilities, all runes visible at level 13 and all passives.
Format is character level - skill - description
