Did anyone else experience problems earning the keys needed to open this raid boss? I spent 4 days worth of energy and daily refills and was not able to earn the last key needed to open the raid. This has never happened to me before. I tried doing all the different adventures in Vanaheim to get that last key and was unsuccessful. Here is my consolation prize: "Unused Raid Boss Key Rewards: 7945 Turn in your unused Grendel Raid Boss Keys for free XP." That is not much of a reward for all the time and energy spent. If I had the key I would have earned way more as I leveled up on the boss. I did not spend any money to buy more energy. Is that what it takes to play?? Katerina
