When a weapon is enchanted with a lash effect, a visual indicator appears on the weapon (e.g. a Burning Lash weapon has a flaming blade.) However, said visual indicator does only show in-game, and fails to display on your paper doll in the inventory screen (I suppose the same applies to level-up, but I haven't tried.)
SAVED GAME: link
Load the saved game.
Observe that the main character has a Freezing Lash weapon displaying a visual effect on its blade.
Enter the inventory.
Observe that no visual effect is on the blade held by your character (paper doll.)
The same steps can be followed with Edér, who wields a Burning Lash weapon in the same saved game.
