the fight is a little confusing
how can I fight better? If I want to win every fight, do I have to go jog every day to get enough hp?
Get invisibility, mana shield, summon skeleton, demon, rat talismans, drain mana. In the buff screen, cast invisibility on yourself and summon everything you can. In battle, simply heal yourself and don't attack. The fairies won't be able to attack you and will waste mana on summons. Then finish them off.
