* Mystical Amplification cast time can no longer be reduced by item bonuses except Staff of Destruction (fixes#903)
* Foresight will no longer stack additively with other cast time reductions (fixes#899)
* Suffragium and Foresight will now be consumed by skills, even if they aren't affected by them
Note: Whether skill-specific reductions stack additively with general reductions and how it works in renewal still needs to be tested, going to create separate issues for those once confirmed.
