In particular, the problem is that a magician without equipment cannot perform any magic. Potions do not require magical powers, although the bonus + 5 to survival from character is good. A high-level warrior can smash faces with his fists. The Succubus' body itself is a weapon. A magician, without a Staff and a book, cannot do any Magic. Which is tolerable game-mechanically, but very sad from a plot point of view. I have already raised this issue in my other topics, but I think it should be highlighted separately and expanded.

I'll write everything down point by point.

1. Firstly, this should not be the default ability. Perhaps as an additional perk, something like mana manipulation, which would allow you to do nice little things like stunning enemies at a short distance by injecting streams of mana into their bodies... or the ability to passively/actively detect magic. – There would be a specialized ability to search for skeletons and NPCs with magical equipment.

2. Secondly, you can use magical enhancements and modifications. Mages love all sorts of artifacts, and the game has them. The Sex Slave outfit is a curse. Cleaning from dirt, but cannot be removed and hold the weapon. Dancer's outfit, equivalent without the curse. However, both of them have a huge disadvantage. They are easy to lose in battle or slavery. In this regard, I would suggest magical tattoos or piercings, but considering that there are already piercings in the game, tattoos would be better in this regard.

2.1 Tattoos. We are talking about spells written directly onto the body. Obviously, it must be quite weak and relatively expensive magic, otherwise many magicians would do this. You can make some nice little things, like spells that work as a temporary lantern at the cost of Stamina and Morale. Or a cleansing spell from Dirt. Little things, very nice.

3. Ritual Magic. You need to add a perk, like a cauldron. More precisely, the Ritual Circle. in fact, the boiler already has some of the mechanics. But here, it is precisely a circle, or a marching Altar, that is created. How to implement? You will need to add 1-2 paint recipes for the ritual circle. Perhaps we should think about Blood in its quality? In fact, this will be a place to create magical items. But not the ones the local Gandalf sells, but worse ones like those given for killing Pighead.

In my opinion, everything seems quite feasible and will not require too much time. In addition to the points above, I would like a unique Staff or Book for the magician, for example the same Necromancy. Otherwise, the Warrior has the Berserker Sword, but the magician has nothing cool or unique yet.
