i found this trick while messing around with cheat engine.
what u will need:
-underrail(ofcourse)
-cheat engine
-basic knowledge of how to use cheat engine
-be under level 23
1. use cheat engine to control your exp. this is very important. make sure to edit your exp so its only 1 exp away from a level.
2. find a place where u could easily gain exp. i choose the spot below the camp.
3.put ur current level in the value bar. click new scan.
4. kill something, gain a level.(u can level up in mid-combat) make sure to complete the level up. that means u gotta put in the stats, skills feat..
5. type in ur new level in the value bar and click next scan. the address list should get considerable smaller, around 4 or 5. result may vary.
6. edit ur exp again, kill something, complete the level up. but this time, look at the value category under the address box. it should be ur new level. example, if u started at level 10, that should be ur new scan. level 11 is ur next scan. and level 12 should be under the value category in the address box. and level 11 should be under the previous category.
7. there u go, now u can edit ur level!
8. have fun!
