Thank you @delegate4gg for your newest update.
Each player can earn a certain amount of bread (6 atm each day) by doing daily tasks. There may be more possibilities in the future. Have you ever considered using bread to reroll at the item store? When you reroll items you can decide what hero (level area) you want to have new items for. Also there will be an update tonight. We changed the item store from 6 to 9 items. I hope with this and the idea of rerolling you will find a good weapon for you archer.
Also something that is more of an emotionally thing because I am responsible for all hero and item graphics, your archer is male :) I know he has kind of a female touch which was on purpose but he is the counterpart to that little girl (see my second hero). :D
Now I want to explain why your level at the arena is 29 whereas your hero1 level is 20. At the arena, we see the level of all of your heros together. For example: My hero1 is currently at level 22, my 2nd hero at level 17 and 3rd hero at level 3. I don't know if you can see me at the arena but under my avatar you can see my level of 42. If you click on each hero below you can see the individual level of the hero.
I know bread doesn't have a lot of options to be spent for now. But you can be sure that there will be more features coming up.
