There is an option in the extras for a steel defender from the drop down, but no listing for the defender itself.  To access the stat block, you have to go into the features.  Additionally, that is a static image that doesnt update with your character.  Is this intended or should there be a steel defender "creature" listing that automatically updates with your pc?

Unfortunately there is no support in the "Extras" menu for anything whose stats depend on the character's stats, which includes Steel Defenders, as well as Beast Master Ranger companions, most summoned creatures from spells, etc. This is something people have been asking for for years, but it hasn't been implemented (yet).

The reason there's a category for it in the drop-down even though it isn't supported is...who the hell knows.

I appreciate the shared sentiment.  I just wanted to post this here in case the design team wishes to see player requests for this feature.

Advice: Create a homebrew creature that is "X's Steel Defender" and update the stats as needed. You might have to delete it from the sheet and re-add later when it improves.

I’ll second that, it’s what I’ve done in the past.

That option exists for the original ERFTLW version of the Steel Defender, whose stats did not depend on the player's.

Was the digital version of ERFTLW changed after the fact? It shows a dynamic stat block currently.
