Modus Veritas Accuracy Suggestion
Instead of having Modus Veritas be hit or miss, it should be given degrees of chance.
For example at base:
Miss/Fail: 10%, Low (50-75% power) 30%, normal 50%, bonus (125-150% power) 10%.
If stacking is still considered an issue and you have a few options.
1. Modus Veritas can't stack and fails. (no thanks!)
2. Modus Veritas can't stack and overwrites. In this case it should only overwrite if it's higher on the above scale. (still not preferred, but tolerable)
3. Change the threshold of the scale if the target is already under the affect of Modus Veritas. for example: Miss/Fail: 30%, Low (50-75% power) 50%, normal 10%, bonus (125-150% power) 10%.
This option discourages from trying to stack due to lower efficiency but doesn't negate the option. The percentages could be slightly adjusted for harder NMs, but you should never let it drop below a 50% chance to land at all, even if it will only land at a slightly lower power. Keep in mind, that Helixes already have their own chance to be resisted.
Plus think of the fun 99 merit tweaks you could make!
