Witches can give you curses

So this idea is quite simple basically the witches would be able to put a spell on you though [A. Only if they are in their hut] and [B. Even if in their hut theirs a 1/10 chance] the animation would be like how villagers say “no” to trading but while holding the same book model the lectern uses. And btw these curses would vary These examples were what I had so far [binding- curse of binding but onto the block your standing on (you can’t move)], [Blindness- your blind], [invinsable- you can’t hit any mob like adventure mode] Those are all I had for now but there are 2 other things [A. When the witch has been killed the curse is removed (and all your item curses as well)], [B. You can get given reverse curses but only for a few seconds such as saturation, healing, regeneration, invisiblity, etc. (VERY RARE)]
