Events are a great way to get Blood Flaked Bone. Rare Catalysts can often be exchanged for event currency or obtained as clear rewards. ..
The Guild Member Shop and the Guild Aid system allow you to farm lots of Rare Catalysts in general. This includes Blood Flaked Bones. ..
Source #1: Adventure Mode – Unrecorded History 8-9 Drifting Tomb (Best Source)
The best place to farm Blood-Flaked Bone is in Stage 8-9 of the Unrecorded History.
This is because the Rare Catalyst is featured in the AP Exchange Shop for Blood Flaked Bone.
Blood Flaked Bone is a new item that costs 120 AP each and can only be bought up to 10 per week. ..
If you want to farm more AP, I recommend bringing along pets with acquisition rate-boosting skills on your farming runs. ..
Source #2: Events
Epic and Rare Catalysts are available for purchase in the Event Currency Exchange Shop during the Epic Cataclysm event. ..
Rare or Random Catalyst Chests are rewards that can be obtained from story events, check-in events, or giveaway events.
Keep your eyes peeled for Events, as they’re sure to bring you plenty of farmable catalysts and resources. ..
Source #3: Guild Member Shop
You can buy a Random Catalyst Chest in the Guild Member Shop for 180 Brave Crests and a Random Rare Catalyst Chest for Commander’s Armbands. ..
The weekly purchase limit for Random Catalyst Chests and Random Rare Catalyst Chests is three per week. ..
You can easily buy both of these chests by playing the game regularly and participating in guild activities.
Source #4: Guild Aid
The Guild Aid system allows you to request crafting materials, awakening materials, and Catalysts from your guildmates.
You can only request aid once per day, and you cannot refresh the request until the following day in case it wasn’t fulfilled. ..
If you plan on requesting Catalysts from the Guild Aid often, make sure you’re donating excess Catalysts yourself to help others out. It can be hard to farm them, so it’s always nice to see someone go out of their way to help others. ..
