How do nebula hearts help me upgrade my virtuous heart?

[CharlieIsBoss]

The nebula heart info says helps upgrade to true virtuous heart. I have Virtuous heart L2 which needs 3 oils and a pile of lower mats. NOW the window shows all that stuff PLUS 8 of the hearts.

If I put the 8 hearts in and all the other items, the evolve window STILL WANTS 3 OILS! as if the hearts were of no consequence. I cannot see how they would help me.

1) Do these nebula hearts only help to a certain level?

2)is there something or some place special that I have to do or see to "HELP" me evolve the virtuous heart?

They are a complete waste of time and resources.  They save you virtually nothing (just a few mats - which you probably have tons of already).

thx for the fast reply.     You called it:  I never even looked at the numbers of all the lower mats, just the oils and the gold haha.   Well if all that does is save a few various crystals, then I agree.   On the other hand, it seemed too good to be true anyway.

If I am looking at the upgrade right it actually takes off one oil along with basically the sacred crystals/soulstone crystals 9and reduced other crystals) so in essence 8 hearts = 1 oil save + mats. It is worth it if you get them from the event dungeons (think there is better uses for the currency), and as long as there isn't a cost reduction very soon.
