A very nice addition to magic tattoos in the Scarred Lands. The new bardic college is nicely done and seems to work very well mechanically, even though more description about who uses this tradition in the Scarred Lands would have been welcomed.
The new tattoos are straight-up conversions from tattoos from the old Relics & Rituals. Most of them work pretty well, even though the Belsameth's Servant could provide more details on how the transformation works from a practical perspective (hit points, ability scores, etc). A couple of them seem to be duplicate of tattoos found in the Scarred Lands Player's Guide (albeit with a different names and slightly different mechanics). A very interesting addition was the use of titan's blood as ink for magical tattoos.
