As Termapain stated, Attract can buy you a lot of time and take a lot of heat off both you and your minions. Terror is another option, just use Terror and completely avoid a problematic area or group of enemies. Confuse is yet another option to keep them busy while you either avoid them, or find a way to kill them, although I definitely prefer Attract.
I know that I've stated this before in a previous post (so forgive me), but Using Decrepify, Attract, and a Clay Golem (or if you must a FireGolem can work too) can seriously stall/delay large groups of enemies. Simply cast Attract on one monster, then Decrepify the monsters around it when they start to move in to attack the Attracted one. Or, since Attract will override Decrepify, but Decrepify will not override Attract, you can cast Decrepify first and slow down their advance and then pick and choose the best enemies to curse with Attract. Preferably the front line of attacking monsters, as all of the other ones behind them will have to run past the Attacted monster(s) to get to you, hence being lured into the trap.
This will A) cause monsters to be affected by Lured to one location by Attract, and B) Since they are then Decrepified, they will take much longer to kill the Attracted monster. Add in Clay Golem's slow affect, and you will soon have a clustered blob of slow, weakened monsters who have lost all intersest in attacking you, so CE, BSpear, PE, PN, Bspirit, away keeping mind to re-Attract, and re-Decripify every few moments. Remember, you can also Attract as many monsters as you want, and freely cast Decrepify on top of any Attracted ones (without overriding Attract), so adjust your strategy accordingly.
This tactic works on almost every single group of enemies that you will encounter throughout the entire game. Also, afaik the minions of Hell are not smart enough to avoid attacking a physical immune monster (as evidenced by them on multiple occasions attacking a physically immune Heart of the Wolverine like idiots), so they should just sit there pounding away to no avail.
