"Don't jump, run, or roll anywhere" I'm sorry, but this made me laugh.
This is a tip: on the wikidot for dark souls 2, it states the covetous demon is weak to thrust swords. If you detoured a little and got the soul vessel from the majula mansion and the Ricard's rapier from huntsman copse, you could kill it in about 2-3 hits of R2/right trigger with your endurance at 20......
But frankly the Covetous Demon is weak. Period. You don't need to respec your character just to beat him.
Save your soul items (great hero, brave warrior) for mass leveling.... No, save your soul items for the one time you go to the bathroom, get invaded and get all your stuff broken by acid cloud and/or corrosive urns, and you lose your souls at the same time.
I don't know man, I get what your trying to do, and it's nice. But I, and a lot of people play very different styles where these tips are going to screw someone up.
My tips would read more like, run past everything, kill boss, eat soul, level endurance (to 20 max until very late game) and either STR or DEX to 40, then worry about leveling HP. Forget magic of any kind. Forget shields, waste of weight. Dual wield rapier or mace to kill bosses fast. Once you hit around level 80-90 and have killed a few bosses, then think about respec into what you want.
