Morgelai Runefencer SU5 (Path C) weapon does not enhance MP gain when using the ability Vivacious Pulse with Tenebrae Runes.


The in game text for Morgelai's augment states:
"Vivacious Pulse" potency +30%
This bonus does not effect the MP gain potency when using vivacious pulse with Tenebrae Runes.

I emptied my MP pool by casting spells, I then applied 3 Tenebrae Runes, removed all other equipment and ensured morgelai was equipped. I used vivacious pulse. I then equipped epeolatry in place of morgelai and used vivacious pulse once the cool down was over and received the same amount of MP from vivacious pulse.

I believe this is a bug because Tenebrae's vivacious pulse mechanic is to reduce the amount of HP restored in order to also restore MP. It is because it is a known mechanic that the potency enhancement from equipment should also enhance the MP return of Tenebrae as divine magic skill does.
