I have a question about the Pack Lord's empathic link ability. In the rules, it simply says the pack lord has this ability and it replaces the 6th level second daily use of wild shape. It does not definitively state WHEN the pack lord gains this ability. We have a druid in our party who is using it at second level, because RAW do not state he doesn't have it yet. However it seems logical to me that it wouldn't kick in until the level of the ability it replaces, so I'm asking for RAW to state that, or at least a definitive statement here to do so, thanks.
Your player is right. The pack lord has empathic link at 1st level, just like a wizard would with her familiar. This isn't the only time a replacement ability comes in before the replaced ability.
