You can get the first ability with 31k renown (only spending 21k of it, but you need an upgraded token which needs 31k), and you can get 30k per day which can easily be done in under an hour. Silver token is 10k, not 31k. That was the whole 21k on the ability but you need 10k for token first, IE you need 31k total. RS wiki page says 10k, and considering it was 1k to upgrade with the first event, I think it's glitched :P Everything is 10* more expensive this time.
