Hail and winter weather

Rune Bonus: You have advantage on Wisdom (Survival) checks made to accurately predict weather conditions for the next 24 hours in your vicinity.

Rune Power: Spending 1 action tracing hagalaz on a willing creature grants it protection from energy (cold) while you concentrate, for up to 1 hour.

Rune Mastery Power (9th level): When sketched on the ground under the open sky, hagalaz conjures a sleet storm centered on a point of the rune maker’s choosing within 150 feet. Sketching the rune takes 4 rounds and the storm lasts while you concentrate, for up to 2 minutes.

Rune Mastery Power (14th level): When sketched on the ground within the area of a magical storm caused by sleet storm, ice storm, control weather (hail and blizzard only), or comparable magic, hagalaz acts as a dispel magic spell cast with a 7th-level slot. If the storm being dispelled is from 8th or 9th level magic, the rune maker uses Charisma as his or her spellcasting ability to test the rune’s effectiveness. Sketching the rune takes 2 rounds.

Rune Mastery Power (14th level): When sketched on the ground within the area of a natural (nonmagical) storm, hagalaz has the effect of a control weather spell. Sketching the rune takes 1 hour and the control lasts while you concentrate, for up to 8 hours.
