For ars-Magica, I've found a few... well, let's say nasty-mean tricks using some spells.
Try a spell that has Fling, Knockback, and Fire Damage, with a Projectile Shape. relatively early-on, all blue. if the Fire Damage doesn't kill it, the being flung upwards AND backwards will certainly irritate the thing you hit. I've named it "Cauterizing Wind".
Also, the spell you have equipped, if it HAS an effect when you cycle to it (Like my "Soft Tug" spell), then shifht-clicking and removing the spells leaves the effect on it. Soft Tug is a simple Touch +Dig +Feather, which is a Vanilla Iron Pickaxe with Silk Touch. while that spell's selected, you can punch out grass blocks, and are given grass. same with punching leaves, it's counted as shears for that.
The White Stone won't save your life if you die, and NO idea what the Bloodstone does, but it charges fast, since I've found the nastiest meanie way to murder Infernal Mobs easily. I set up a 15-block deep pit, it's about 5x5, and I've set a Daffomill, and a Mana Pool with Sparks nearby, blowing towards a Dynamism Tablet that I've set a Cursed Spirit's Blade on. The Blade has Unbreaking III, and Sharpness V (Was a PAIN to get all that xp). What happens is this. at the top-middle of the hole, when I was preparing it, I set a "Mark" there. I have a ranged AOE Recall I explore with. if I find a mean-nasty I can't kill easily, or an Infernal with Sticky, I zap them with the spell, and my Hungry Chest and Golems collect the loot from on top of the spikes near my Tablet. Besides needing to remove and repair the blade every now and again, it's mostly foolproof. I've made the walls of the pit out of Obsidian, with a single grass block under the Daffomill, which is set in a way that endermaynz can't get to it :3 It's one of the worst things to do to a mob, but it's STUPID fun to show those Infernals what-for.
Also, have about 5 artifacts that upon using them on a solid surface, make a cake there. I NEVER am going to run out of food :3
