If they decide to develop sorcery as an element of player gameplay, I really hope the devs keep.a mind toward how it is usually presented in the Conan stories.
Magic is usually extremely rare, risky and complicated. It usually involves heavy rituals and high costs. When magic is presented more"casually" it is limited to the realm of illusion, scrying, and lesser enchantments. Mesmerism, clairvoyance, the occasional invisibility or other trickery are usually about as far as it goes.
Magic is almost always potentially dangerous to the caster and failing to cast carries the risk of corruption, backlash or even reprisal from the extra-planar beings involved in such magic. Even when successful magic leaves its mark on the caster in terms of life, limb, or at least the ever-growing stain of corruption.
