Overview[]
Rare Ancestral Weapon Shards are shattered weapons that can be restored into usable weapons at the 
Ancestral Forge or fused with other ancestrals at the 
Fusion Forge. They're randomly generated, including their names. While they are considered to be tier six alongside merciless iron weapons (Gear Level 18), they are more powerful (Gear Level 20).
They are guaranteed to drop from Lesser Blood Souls and can be purchased from the southern Vampire Merchant for 
750 Stygian Shards each. They also have a chance to drop directly from completed tier 1 Rift Incursions and sufficiently high-level V Blood Carriers.
They're infused with 2 random attributes in addition to their random Spell School effect, causing secondary Weapon Skill (Q) hits to inflict
Leech / Ignite / Condemn / Weaken / Chill / Static.
Unlike 
Epic Ancestral Weapons, they can be upgraded twice at the Ancestral Forge by using a Dark Silver & Sanguine weapon of the same type. Doing so increases the ancestral weapon's tier, Gear Level (20, 24, 27) and physical power (19.9, 24.3, 29.3) while keeping their ability modification and attribute stats.

Crafting[]
Rolling a Specific Rare Ancestral Shard[]
Given that there are 6 possible infusions, the chance to roll a desired one is 1/6. (16.67%)
Given that there are 14 possible attributes, and you get 2 distinct rolls to obtain your desired one, the chance to roll your desired attribute is:
Thus, the chance to roll a rare shard with a specific infusion + a specific attribute is: Which is the equivalent of about 1 in 42 weapons.
