Can you still get 8 modifier maps as an outcome when corrupting?
Yes.
Hi, We have a fix for this coming at launch (we enabled Dynamic Culling for the skill so its performance should be better if you have the setting enabled).
For clarity, in our livestream we mentioned that Sacred Wisps would always trigger when a Rare/Unique enemy is nearby. To avoid performance issues, we've reduced their chance to trigger but have increased their damage to compensate.
