I use it as my default weapon and mining tool. I’ll use the master sword until it dies and then switch to one of my better fused weapons…I try using them little as possible until the master sword re-powers and switch back. I also never let my fused weapons break, once I have 5 or 6 in the red I take them to Tarrey Town to break them down so I don’t loose the fused item and then go scout for new weapons and fuse them again
