Hi, i cannot feed up first sister heart because to feed it i need 150 nerva, but with my 4 hearts i have only 130 nerva capcity on each color, and i cannot move to another chamber to complete brothers mine quest.

So i'm asking what i'm doing wrong?

I cannot understand what the problem is. Why are you talking of nerva capacity?

I can store maximum 130 nerva, but to fill sister heart i need 150.
Is there any way to maximize my nerva capcity to 150? or minimize sister need of it?

Thing is, you can use multiply colors. You can use the two colors that they'll accept. The first sister's colors being Gold and Emerald.

Also, if you just want to use one color, you can fill up the Nerva container, go to her garden, deplete it on trying to feed her, and then exit the garden to the Void to let the Nerva fill up some more so that you can give her the rest.

YOU DON'T HAVE TO GIVE 150 COLOR ALL IN ONE GO.

Yeah I know that but if I trying fill let's say 80 nerwa to her heart it's simply not work,
i painting donor glif on her, this bar is filling to 80 but when i release mouse button, nothing happen, her heart its still empty and i have full of this color.

May it be some kind of bug? Or I'm doing something wrong?

Sounds like you are drawing the donor glyph wrong. Easily done because neither the video not the hub symbol emphasize what is needed for the glyph to be recognized. Be sure to draw it large enough that the game will recognize it as a glyph, and make sure that the tails are straight and extend both above and below the round portion

Hehe you're right now works, its must be big enough i think, strange because when I painting it on trees same way i never had any problems.

Thanks for help. Topic can be closed.
