The 'lose stamina' or 'appearance' from magic is fairly common in stories. Its probably in the bottom half of the Top Ten of magic limits in stories. Even D20 has 'lose a year of life from casting a Wish spell' which is a possibly milder variant on this.
Which is to say, there should be a world created in which Stamina Loss magic is taught because its just so common.
Probably the most common is 'physical involvement' followed by 'exhaustion-varying by power of spell' followed by 'loss of materials'. Of course, 'time used' and 'visualization required' fit in there too. Maybe 'exhaustion' is most common because it happens in magics where people toss down smokes and powders, but it also happens in magics which are purely mental.
One interesting world might be a world of oh...four types of magic.
Stamina Loss is paired with Extra Effect. High ritual is used as well, along with time and frequently apprentices. This loads up the spells with lots of power, and then that gets expended in part by success, and in part by making the spell massively effective....call these the Thaumaturge Guild. Hiring them is very expensive, but if you need a castle blown up, they're cheaper than hiring an army of mercenaries. They typically only talk to nobles and professional scholars being elitist types.
Rhymespell is what is taught in the villages and among the peasants. Its quick, simple, and largely weak. A visualization, a quiet poem of four lines, and bam...magic. Maybe. Its also by tradition, non-visible. Skilled practioners are called Rhymers and Bards.
The Lightwand use a personalized wand of ash, and heal, and drive out evil influences, and bless crops. They are arcane magicians devoted to holy ends. Their official name is The Order of the Lightwand. They are sometimes called 'Ashworkers' as they use Ash trees, and also use basic fertilization in addition to magic (in many of their works, their is less magic than it might seem as they use basic tech also). They are known for spreading ash on fields to help fertilize them, and using ash to purify water. Much of their magic is ritual, and individualistic, but they do have combat magics which are quick, and powerful. They achieve this by enchanting their personalized wand with spells that can be released by Will and Word.
Power Mages is what they like to be called. Dark Magi is a close second. Most people don't say their name, but only indulge in one of the offshoots of the Rhymers which is an ancient dying tradition of hand magic. They form a hand sign to ward off evil, and that is what these are known by.
They get power from blood sacrifice, usually from others, and frequently from unwilling others. Animals, people, special types of people, and finally from their own selves are the Four Categories of Blood with each yielding more power. Frequently, their spells must be cast at night, and upon 'holy' altars. They summon creatures to carry out their wills. Some of these creatures are not explicitly malevolent. In some worlds, a Giant Scorpion is merely a normal predator, but summoned here it is a threat to any near it. Worse, it can be bound by magic to a purpose.
Of course, some of the beings summoned are explicitly malevolent instead of just predatory.
The typical response of the other groups of magicians is TG ("Raise a mighty curse to shatter their works for seven generations!"); Order ("Send forth a magi to track them down, and destroy them.); and Rhymer (...wish ill upon them...) and Bard ("Lets grab our pitchforks and torches and burn them out!) so they tend to hide especially as they are poorly suited to direct conflict with all but the weaker Rhymers. Instead, they weaken a country, and gather supporters from the downtrodden and over-ambitious created by a country weakening, and eventually raise a host of horrors to ravage the Guild and the Order and burn the villages and turn the King of the land into an undead zombie.
Which is to say that they're are a few wildernesses thick with monstrous things where the Power Mages had their way, and basically depopulated the land, and turned it over to Things in the Night.
