Impale for fighting tough mobs, and reducing their hp regeneration rate. Plus, if you're lucky enough to get the titanium spear + spin + autumn harvest, you can pretty much regenerate your hps back to near full. Then switch over to swords and dish out some damage. Get amathylar if you're lucky, for additional healing. Tack on black hammer pendants, and the sky is the limit. Add in the fact you have inherent stone skin for especially tough mobs, plus magic/disease/poison resistance.
