All I have to say is fuck those Skeleton Spinners.
falling on them from above is my new favourite pastime. In painted world, do a quick jaunt through the first few steps of the area, then break for the ladder making sure to take an angle other than what the enemies come at you on. Break up the ladder, then lock on ...you canhurl fire, magic or lightning down on them or simply drop on their head with a good weapon like lightning spear. If you didn't get them all the first time rinse and repeat. The ones in teh halllways are easy to peg one at a time as long as you know where they spawn and are ready to get them before they get you. Entering from the well in the courtyard is easier IMO. Just keep te illusory walls up as long as possible so that they don't gank you....one on one they are not as tough, especially if you hit them BEFORE they start rolling at you!!! Eagle shield helps but is not foolproof!
In catacombs, one option is to drop down where you can summon Leroy....he will get them goin sometimes, but not always.....the best spot is where the black night spawns as it is esier to get the skellies excited by shooting arrows at them....then when they come over and spaz underneath you you can get the whole whack of them in one drop...i fgured this out on my own one time and killed every last one in one drop ....fuck that felt good....died too many times to those fuckers!
