+#### Armor_feather
+***"Armor_feather"*** will slow a player when falling. This only has one level or state, which is armor_feather=1
+
 ### Physics
 The physics attributes supported by 3d_armor are ***physics_jump, physics_speed and physics_gravity***. Although 3d_armor supports the use of this with no other mods it is recommended that the mod [player_monoids](https://forum.minetest.net/viewtopic.php?t=14895) is used to help with intermod compatability.
