Crests are inlays now

How Crests work in The Ember Depths 0.21: inlay one in any socket to amplify the runes around it, how many inlays you get, and what stays the same.

Your 13 Crests keep their levels, their drops and their awakening at level 15. What changes is where they go: a Crest is now inlaid in a socket of your Brand.

Amplify. An inlay strengthens the rune lines of its socket and the sockets touching it (up to 7) by × (1.05 + 0.003 × Crest level): ×1.11 at level 20. Overlapping inlays never stack: a socket takes the strongest.
Its own line counts the ranks in its area. The Heart has the biggest area and an outer corner the smallest; the card shows the number.
How many. One inlay, plus one for every Great Bond, at most 5. If you break a Great Bond, the newest inlays go dormant and wait; none is ever removed.
XP. Every inlaid Crest earns XP from chart bosses and Breach Wardens.
Your starter is inlaid on the Heart at the Awakening.
