1. get both hermit's students gifts, so hermit will launch a lot of fireballs 2. levelup till you reach lvl39, NOT more! 3. go reset time. it would be best to have enough money to reset time again in future (you can count in 50 coins you will get from hermit) 4. go train with him, but run away to the left side of the... umm... battlefield constantly. your goal is to stay on this screen, not running away completely and not attacking hermit himself 5. do so till there will be 4 seconds left on the timer. attack hermit then. you will levelup to 55-60+ level instantly. 6. go reset timer and attack him finally.
I don't remember and i don't believe it really matters here: you will have your 'sucky hero' rating anyway, and i doubt you will be able to levelup too far beyond 50 mark. My limit is 55, someone in the halfminuteheroes.com site got 64th level and i have not a slightest idea HOW COME: hermit challenges you as soon as you reach level 40, and he fires his fireballs at constant rate, so being pushed back or rushing doesn't make any difference, since you will hit roughly same quantity of it.
i beat hermit by getting only 1 of the food items for him you can fight him very fast by dashing to him and using herbs to replenish your health getting only 1 food item levels you more slowly, but allows you to level up beyond 40 so i leveled to like 50+, and equiped heavy armor (you need armor so you wont get blown away by his shots)
