FYI y'all. vs the chickens at 24:00, Serena has 16 resist so 0 chance of getting turned to stone by -2 resistance penalty of cockatrices. also no need to waste mana on prayer even if following the Don't Let Them Touch You strat - Serena just had enough mana to blast down 2 Behemoths and 6 Earth Elementals for Freya's sake!
"If a hero approaches you through the normal hiring routine (not summoned) and you reject it, the next time the hero appears it will have gained a full level of experience, as it spent some time adventuring after your rejection.
