Background: nacre/mother-of-pearl is a strong composite material produced by mollusks, with a greater compressive strength then human bone but a weaker shear strength.
If an entity were to have bones that were composed of both bone and nacre, how would it interact with the world differently? For instance:
said entity can jump from higher heights without damaging limbs, provided that they land in a way that channels the force of impact parallel to their leg bones, rather then perpendicular to it
said entity can punch harder without breaking or damaging their arm bones
For the purposes of this question, let's say that this entity can regenerate bone tissue as effectively as "normal" life can, and that its connective tissues are proportionately durable (say, made of resilin).
