Buffed Tools Mod 1.7.10, 1.7.2 created more for a tutorial, then to be an actual mod. But it makes the game a little bit different, so you may want to include it into your modpack. Buffed tools adds the "buff" system from Terraria into minecraft. For those, who are unaware - the system makes it so when you craft any tool, it will get a random set of buffs - or debuffs to it - making it stronger or weaker.
