so why they do not posses powers similar to mages in the end? i mean why Vaesemir for example wich is super old, older than yannefer and way older than triss still have basic magic powers like all other witchers? why does gearlat that's now more than a century old and also older ( albeit by not mutch) than yennerfer? i mean they have the magic skill,they have time and they obviously are not stupid since they have a comprhension of alchemy and mutagens that's sometimes way above the everyday mage, they spend all the time since they are very little to train at Kaer Mhoren the art of the sword and the lore of the monsters they will hunt, and also alchemy for witcher elixir AND magic to learn the signs.so why exactly do they stop at some point? why don't they kke training in the magic department to so they can be super powered swordsmans AND ultra skilled mages? woulden't this eliminate any sort of treat even from very strong monsters like the one i listed above? woulde'nt theyr job be mutch easier and also theyr general life too? a mage is seen as someone who could easily kill a dragon with the right spell and yet they are complete tools that can be killed by a single strike at the right moment ( seee vilgefortz for example) immagine how insanely strong someone like letho or geralt could be with the powers of a mage? they don't have to be villgefortz level powers even a level of power like the one of triss or below would transform any ordinary witcher in an almost invincible foe, i repeat, immagine someone like geralt o re letho! so again, why non of the witchers ever tought about this and instead they keep letting those mages insulting them and stuff? we know that the mutation grants them magic powers,since thay can use the signs, and witcher can improve the power of those signs if they focus more on them. also they age very slowly, so slo in fact that they can be compared to elves and even mages. compared to a normal human and also way more resilient to damage,immune to diseases etc.
witcher are mutated to be super strong,agile,quick etc. sometimes this monsters are super strong and posses magic powers to some extent like for example bruxas or succubus or very powerfoul wraights/spirits like the wild hunt etc. Nwitcher are mutants, they are created to be killing machines hunting monsters. Why our magic powers are so limited? why witchers only posses a bounch of very basic magic powers? but let me explain Now this is perplexity i have not only for the games but expecially with the books too
