Checked by myself.
The mod works just fine.
The damage is just not shown, you will one hit every enemy depending on your damage multiplier but it will only show the maximum hp from the enemy as the damage. But as you can see on the screenshots below, you deal a lot of damage.
The "unlimited currency" mod also works very well.
The feature does not work. The currencies were still reduced and att multiply does not kill monster as you said it would. The visual didnt change and the amount of damage dealed were the same even with x100
