Well, iirc, Star Potions are one of the potions you can get from her. Those can make golden whetstones.
yes but not only golden whetstones also curses and non-golden whetstone items
But if you have 1000 hp and passive healing, paying 100 life to fill up on star potions isn’t a big deal.
once curses start doing 500+hp you will think overwise, its a death sentance
