How much ISO needed to Max A 3* or 4*

Been saving up my ISO (260k) as of now.

Does anyone know how much ISO it costs to fully level a 4 star character and a 3 star character.

Thank you

3* is about 172k.
4* is 400k+

Polarity’s Guide on Going From 1* to 3* has an ISO calculator link in it.

From 40 to 166 is 172,764 for a 3*
From 70 to 270 is 434,462 for a 4*
From 70 to 220 is 247,978 for a 4*. 1.5x the cost for way more than 1.5x the value of a 3*.

My spreadsheet (cribbed data) shows:
2* → 94 = 69,524
3* → 166 = 172,764
4* → 270 = 432,467

The only exception I know of is Devil Dino, who gets levels at a 20% discount relative to other 4*s.

My Xforce is somewhere between 213 and 217. Seems like I will keep him on the back burner for a bit…190K iso is pretty brutal (especially when you play so seldomly that 4-5k a day is about the norm).

He does? Never knew.

love how to know to play Seldomly but still pull down 5k a day.

And didn’t Colog post his rough guide on ISO farming via LR?

Please, D3, cut the costs of leveling characters. That is just absurd…and to get 3-5k a day via DPD is nice…but honestly a pittance against the actual cost of leveling the character when you do get a cover you need.
