feeding them sentient cores is not a solution i recommend. I fed mine 300+ Flawless cores to reset it all to neutral for it to just immediately hate anything you feed it again. It is an exorbitant waste of cores

theres one of the combos on SO that does a spin move which hits a bunch of times which is really useful for building combo fast and proccing all sorts of status. and i think theres another combo where if you do just the first attack of the you throw them in front of you and they spin and hit enemies a lot of times which is also really good for the same reasons i already stated but I could be wrong since I don't use tonfas all that often, it's just what I've noticed.
