Been doing some testing with the cube rune vs base effects, and they are very underwhelming. I can confirm that the cube rune is working as intended, but the problem im highlighting is the base effects of the illu spells. Here are examples done against 51% mr and 103% mr to show what im talking about:
Shock :
- stopwatch timed at 27 seconds duration (20s spell + 8s effect on last pulse)
- mr reduction supposed to be 25% of current mr (as per tooltip)
- mr reduction at 103% jumps down to 88 in first second then back up to 93
- stays at 93 for the remaining 26 seconds inside cube range
- mr reduction at 51% jumps down to 37 in the first second then back up to 41
- stays at 41 for the remaining 26 seconds inside cube range
- appears to be a flat 10% pulsing effect, but dont understand the dip at first second (bug?)
Conclusion - review of 10% effect, not impactful enough for a 55mp casting spell. Illu burns a lot of mp casting multiple times. Suggest to put back to the original 25% effect.
