Then it's quite hard to trigger that tumble effect I suppose. Drop rate of runes are always random, even if we could dissolve 3 group of runes that's already consider a rare chance.

Even with Heimdallr's active skill activated, I also know that the fire rune's drop rate is poor unless for the first batch you could dissolve away much more runes.

So the easiest way is to use Cao cao's active skill or put more fire runes converter then. Cerberus, Black Cat and similar cards will do.
