My sword damage against bosses was 9 and when I purchased demolition sword, it did not go up. The ascension upgrade does not say that it is not for bosses whereas wipe out bow specifically says small enemies. Therefore, I assume that demolition sword should increase damage against all enemies by 20%

If it doesn't say bosses specifically then it's not for bosses

As described in my original post, it says specific enemies in other upgrades. It only makes sense if it does not mention any enemy types, that it is applicable for all.

The other upgrades don't mention specific types (any more), that's what we talked about.
