This spell causes characters entering the affected area to suffer extreme allergic reactions. It may be cast on any field, meadow, forest, or other outdoor area with an abundance of plant life, causing the plants to produce pollen, antigens, or similar allergens. Characters coming in contact with the affected area who fail their saving throws vs. spell, experience swelling of the eyes, fits of sneezing, and dull headaches for the next 2-5 (1d4+1) turns. During that time, they make all attack rolls and ability checks at a -1 penalty.
The spell affects a cubic volume whose sides are 5 feet long per level of the caster; thus, a 9th-level caster could affect a 45'x45'x45' cube. The spell lasts until the end of the indicated duration, or until the first frost, whichever comes first.
The material component for this spell is a pinch of ragweed.
Notes: Uncommon for rangers, rare for druids and other nature priests.
