GAME STILL CRASHED, HOW TO SEND LOGS?
Go to folder /Android/data/game package name/files/mod_menu_crash_logs.txt
Copy & paste or take a screenshot inside the logs, send it here
Some device may have different dir (document files)
Alternative way: Install matlogs app (required root device), open matlogs & click start record. Open the game wait for game crashed or few minutes and stop record.
So far what i've figured out:
1. Damage multiplier is an "imperfect" hit multiplier. On some skill it multiplies your hit count, on some skill it multiplies your projectile counts (drill and ball), on some skills it doesnt work at all (molotov). You want to blow up your phone? then pick drill skills + ball skill + lightning skill + 50x damage multiplier
2. x2 loot multiplier works on gold mine. Any higher than 2x then it will gives error.
2a. It didnt work on regular chapter. Im on chapter 50. Ive tested x2 loot multi with godmode in chapter 20 and its giving me error after completing battle.
2b. Didnt work on daily challenge.
3. Mod doesnt work at all in Enders Echo (ranked mode), which is good. No matter what feature you turn on, you will always get error after completing battle.
