Stormshaft

Weapon (any thrown or ammunition), uncommon

Attacks made with a stormshaft weapon are not adversely affected by wind effects (GM’s discretion as to what a wind effect is but examples include the effects of the gust of wind spell or an air elemental’s whirlwind attack), whether natural or magically created. A stormshaft weapon deals additional damage in an area of strong or stronger winds, adding +1 damage of the weapons type per category of wind strength above calm (use the control weather Table: Wind as a guide).
