Ultimate/Premium Rune Gems

Whats the fastest way to obtain Ultimate Rune Gems. Can you guys give me tips or suggestions.. I'm trying to make Premium Rune Gems for my Hippo. thanks!

Tbh Team modes and challenges, there's no quick way you just have to get lucky:(

If you're a complete die-hard, you can farm Honor all day, every day and buy Gold Chests+Keys.
The chances are slim, but you'll get more Ultimate Rune Gems than usual.

If not, then I'd say Team mode and Expert runs are your best shots, as FrenZy said.

I personally have seen more ulti runes on FC,Swamp teams than on HR or BL team modes. Expert wheels for me don't show many.

Its all just luck,
You could farm levels like sea-3 and Bl 15 normal for chest squares, Get normal and green runes and fuse them up too, but thats a lot of time.

Runes from expert runs? How!

Just team mode , the best and fastest way to get them , be patient by time you will have a lot.

When you arent looking for them they pop up everywhere
