Tinkers Tool Leveling adds a level up command, but I don't remember what it's called. At least it did in 1.7.10 when I last used it. FTB Utilities apparently adds an NBT editor if you want to edit the information stored on the tool. You could also use ore excavation and go crazy in the nether, which can max a tool in about 5 minutes. This mod is like that, except for Tinkers' Construct Tools and the cheatcode takes longer to enter. Gives your Tools XP, allowing them to level up. On levelup an extra modifier is rewarded. You get xp for doing whatever the tool was intended for, so breaking blocks with pickaxes, killing things with swords, etc. When a tool is created, Tinkers’ Tool Leveling Mod 1.12.2/1.11.2/1.10.2 will create a fixed number of Modifiers and increase the Modifiers as your tool levels up. In general, the EXP at the later level will be double the previous level and there is no upper limit at the moment. This is the 1.7.10 port of Iguanamans Iguana Tweaks for Tinkers Construct. It is a Tinker's Construct addon. Minimum required TConstruct version is 1.6.0d38. Tinkers' Tool Leveling. Mods 36,795,082 Downloads Last Updated: Oct 23, 2018 Game Version: 1.12.2.

You know back in the days, when you played GTA and used the cheat code for a tank, and then went on and caused mayhem? This mod is like that, except for tinker tools and the cheatcode takes longer to enter.

Note that swords get xp relative to the damage dealt when the entity is killed, not when the damage is dealt. You only get xp if the mob is killed.
