*Cagliostro's immortality works on a revival system, her current body has to completely cease functioning before she can craft a new one and no matter how injured she is, as long as the current body is still alive, she can't create a new one but has to focus on healing the old one. Her soul can easily be damaged by being out of the body for too long and thus needs to reside in the tiara to prevent dissipation of the ego. Any new bodies will be made in the general vicinity of the tiara for this reason.

*Her alchemy can only activate by being physically touched by her hand or having a magic circle projectile that's flung from her book to make contact with whatever she's attempting to modify for it to work. She can't reshape any material she doesn't personally know the composition of, and generally any such alchemy performed in this manner will be on a broad scale and not at all finely tuned. She can craft giant iron stakes or craft a rough throne out of stone for instance but if she wanted to do something like create a working firearm with all the fiddly bits, it'd take a lot more time and energy so using it in combat is moot. The only exceptions to these rules are her backup bodies and her Ouroborous homunculi.

*Her regeneration ability can potentially recraft lost limbs and organs, though it'd be a slow and painful process that'd take a few minutes to hours in general depending on what parts needs replacing and she'd need to transmute elements from her surrounding to replace the lost mass. The same goes for her general alchemy too. One can't craft something out of nothing after all due to the law of equivalent exchange. 

*Cagliostro's physical limits though higher than average for someone of her age, is still ultimately human in nature whether it be strength, speed, or reflexes. Her mental endurance is much higher than average due to knowing pain that most people would never experience without actually dying many times over. All in all, one can simply overpower her quite easily and she has no sensor ability whatsoever so sneak attacks are one of her greatest weaknesses as well.
