Storm
Hagalaz (ᚺ), the purple rune. No hero and no realm claims Storm, and a standard journey never deals it at all — you will only meet it somewhere the colour set has been widened.
In detail
Block 7. Note that the Bottled Storm consumable deals Lightning damage rather than Storm; the two names diverged during development.
