Sacrifice strategies?

[zdm-1083]

Hi,

I wonder how you sacrifice?
Did you upgrade all toon? Only some?
Which level of reward did you go for?

On my side:
- I keep 5* for 50K sacrifice meaning also that I keep 2 natural 4* maximized to go with as well as two 3* eddies :]
- I go for 2K reward with max level 3*
Other is trash sacrifice at level 2.

Right now I do not have so much natural 4* may be later I will have enough spare to go for 9K...

But I saw Jofer post like this:

Yeah I focus on efficiency. Also pro tip, 10x 2* is better than 4x since you get 3 drops at the halfway point with 10 instead of 3x 4 at 12. Best is getting 3 rare souls from 10 2* Guessing you hadn't realized the halfways give 3x the rewards.

I wonder if I do it the right way XD

And you, how did you fill the vortex?

As a reminder:
7 50K+
6 20K+
5 9K+
4 6K+
3 2K+
2 500
1 100
