Application of this spell increases the Strength of the character by a number of points - or tenths of points after 18 Strength is attained (only if the character is a warrior).
Benefits of the strength spell last for the duration of the magic. The amount of added Strength depends upon the spell recipient's group and is subject to all restrictions on Strength due to race and class. Multiclass characters use the best die.
A Priest gains 1d6 points of Strength;
A Rogue gains 1d6 points of Strength;
A Warrior gains 1d8 points of Strength;
A Wizard gains 1d4 points of Strength;
If a warrior has an 18 Strength already, from 10% to 80% is added to his extraordinary Strength roll. The spell cannot confer a Strength of 19 or more, nor is it cumulative with other magic that adds to Strength. Beings without Strength scores (kobolds, lizard men, etc.) receive a +1 to attack and damage rolls.
The material component of this spell is a few hairs, or a pinch of dung, from a particularly strong animal - ape, bear, ox, etc.
