What feature or spell has the most misleading flavour, or biggest flavour-related failure?

For example:

Flame blade (The 2nd level spell) sounds like a spell that creates a weapon, and even flavour-wise, it says that it creates *something similar in size and shape to a scimitar*. But doesn't actually create a "weapon" with weapon stats.

Another similar flavour failure is hunger of hadar. It creates a sphere of blackness that can't be illuminated, but it doesn't specify whether it's dark or heavily obscured.

These two cases show different sides of the same coin. In the former, you have to rule against it creating a weapon, while the latter low key expects you to rule in favour of it creating either darkness or heavy obscurement.

Edit: Have you ever reflavoured or redesigned any spells that either appear to have missing mechanics, or have flavours that don't match their mechanics?
