Ok thanks, i just want to save some Sanity points but the gain is ridiculous beyond 200 kills.
And i think i made some mistake in my post.
But i am sure, i made the right calculation , i always used auto batlle (with the same map, “Lungmen Outskirt”), except for the last Annihilation to complete my weekly orundum.
Maybe 5 times this week, so it was 1625(5*325) orundum and i needed 75 as you can see.(not 170 sorry)
I made 199 kill excactly before quitting, and i have 1690 orundum now.
Something was off since last week, but it’s not important to save 10 orundum, i’ll just use the auto battle next time.
