It has always been that the name of a rune had to match the spell name of the dragon exactly in order for the rune to provide the stated boosts.
(Other than wisdom and rage that can be applied to any dragon.)
There was a discussion back in December where it was said that the Rune of Pride obtained from Leo’s event line works on any dragon.
Can someone from PG confirm this please? If this is true, what other runes are not specific to intended dragons? Thanks!!! @PGJared
