You can also unpack to a safe directory the Data0.pak file with 7zip and edit the various player skills files. For Logan that would be logan_skills.xml. Then put it in the documents folder (Riptide-out-settings-data). If you do not have the "data" folder make one. There are a lot of interesting things you can edit in that pak file. Always keep backups and, like any programming, watch out for those ; and "" etc.
You cannot exceed "1" for this skill, so for the three tree upgrades that refer to the boomerang thingy, you should make the chance to retrieve at ".33", or two of them .33 and the last one .34, thus giving 100% chance of retrieval after you have filled out your skill tree.
