its 10k silver to feed 6 uncommon into another champ :s 

you'd need 16 million silver(which isnt much) to get rid of 10k shards .

Also , if i may ask , how many green shards do you have to run out of silver trying to empty them ?

Edit: dont get me wrong , i do find opening many many green shard tedious but they still decent pts on summon rush and champion chase events ..

Its not the summons that i have issues with, but I burn through silver doing other things, like upgrading equipment and leveling up 5 stars to 6 and getting them to 60.

I do wish there was an ability to turn x number of green shards into a a brew as long as you got the summon credit for summon events. I would even be more than ok for the brew you recieve to be random and a little less leveling value then going through and feeding champions to other champions. It would just be so nice to be able to select 1K shards and turn them into X-brews. 

For gnut I used 3 sacreds and maybe 2-3 k greens.  Actually I think I used the sacreds just to pick up leggo books at top milestones.

2 issues 1) time required to eat all those greens is nuts.  There was a rather sailor t point a week or so back suggesting a way to corr this.  There absolutely should be a qol upgrade here.

2) silver to do it.  That's a logistical factor that you can, or should, or eventually will figure out on your own.

I did same click fest. My index finger is worn out :D

Thats why i wrote before, shift+click in win client should be nice, select multiple characters at once. Or at android client long press, just same when select multiple things or long text to copy to clipboard.

This will happen right after we can fuse rare books into gold :)
