Runeblades

One of the six families a delivered blade can grow into at +10. Its final form at +20 is Akasha, Blade of Genesis.

A blade only joins this family if it came down the lane that turns it into a Shard of Magic at +6 (a Awakening Blade at +8). At +10 a hidden coin flip made on delivery sends it here or to the Splitblades, so half the blades from that lane end up in each. A sword bought from the merchant as a basic sword rolls its lane and branch at random.

A Great multiplies value by 2.5 rather than the 2.25 that two levels would give, so a blade that climbed on Greats is worth more than this table.
