I would, but this actually spoils some of the surprise involved with the blacksmiths' quest. To get it you need to give the smith their key, defeat the giant rat in the sewers and unlock the door at the beginning of the sewer level with the giant rat key.
The growth speed just affects how long the animations run for, so for example instead of something growing slowly for eight seconds, it will finish the animation in three.
