Is this new "Substitute Wood" anything like Viagra?
You should create a Stand Alternate where it's not floating around. That would provide a whole new way to use this. I like that it splits apart in the death animation, that would be very satisfying to see in-game. Although it might be a good idea to have the chunks fade away, shrink, or something; having them just abruptly disappear just doesn't look right and literally annoys my eyes.
Anyway, this definitely has its uses. 3/5.
