This is going to be a simple guide for anyone who is trying to go for 100% achievements! I love Idle games and I am a fan of going to 100% at all times, but i realised i was done with all achievements but the Legendary one, very quickly.

Quick math, 1% drop rate (smiley) at 90mins per attempt 20 pulls 5% each for 100% drop. is a veryyyyyyyyy veryyyy long time. 4+ months going on years. Personally...and no disrespect given, ♥♥♥♥ that.

Thanks to Manual saves, you are able to screw around a bit with them. I noticed each reload of manual save the drop rewards of legendary bosses are different. So you are able to get the drop you need by reloading over and over and over, forever. You should manually save before you pick a boss to kill. and kill it. Oh you didnt get the drop? reload and try again till you get the drop, and then RE SAVE to make sure you are ok.

Now you can do this and wait the 30mins, 1h, 1.5hour time limit on each boss and farm it that way, butttttt here is a bonus thing for you;
If you are using Cheat Engine. You are able to have 1 item (midus touch) at level 5. and a 2nd midus touch since you killed the boss again but DIDN'T merge it yet. you are able to search for the number 5 in your cheat engine, then merge them, (please save manually before all this) and do a 2nd search for 10 (in this scenario) and you should find 1-5 addresses with the number and try 1 by 1 till u see the number go to 100. and repeat that with each legendary boss.

BONUS TIP!
Idk if its just me, but i noticed that the smile guy, first boss HATES reloading from a save file? You would kill him but then nothing happens to him and you are sort of soft locked till you load a save file/close game and restart it. so just know that is a common thing and don't be scared!

Goodluck getting 100% <3 :3
