   modifiers rather than one `armor`-wide one, so a weapon reads as a held bonus
   instead of claiming something "when worn". They stack per module - a piece
   built out of arcane essence that also carries an arcane gem counts twice.
+- Titanium adds `miapi:generic.elytra_glide_efficiency` on the chest. Heavy
+  armour subtracts `-30 - density*2` from that stat, so this hands a little
+  back rather than cancelling it; titanium's flexibility is nudged up too,
+  since Armory's wing modules read flexibility and density for glide.
 - Cinder essence uses slot `any`, so one gem grants fire immunity wherever it
   sits, worn or held. The attribute caps at 1 and the handler treats anything at
   or above 1 as immune, so extra pieces neither add nor dilute.
