I was wondering if a purple statue Power Stone could increase our luck to get some prototype modules for the weapon lab ?
The simple answer is no.
The purple Power Stone statue only increases the probability of receiving Power Stone's not prototype modules.
There is an 8% chance you will gain a prototype module by completing one of the following :
- Destroying Mercenary Bases
- Destroying Blackguard Bases
- Destroying Dr. Terror Bases
- Winning the Hammerman Strikes Back events
- or by Achieving Reward Thresholds in Colonel Gearheart events
However you must first construct a Weapons lab before you can collect prototype modules. The only exception to this rule is the War Factory event.
This 8% chance can not be increased in anyway.... as yet.
