Application of this spell increases the strength of the character by a number of points — or tenths of points after 18 strength is attained and the character is in the fighter class. Benefits of the strength spell last for the duration of the magic. The amount of additional strength accruing to a character upon whom this spell is cast depends upon his or her class and is subject to all restrictions on strength due to race, sex or class. Minimum-Maximum Class Strength Gain CLERIC 1-6 (d6) FIGHTER 1-8 (d8) MAGIC-USER 1-4 (d4) THIEF 1-6 (d6) MONK 1-4 (d4) If a fighter (paladin or ranger as well) has an 18 strength already, from 10% to 80% is added to his extraordinary strength roll. All Strength addition scores above 18 are likewise treated as 1 equalling an extra 10% on the extraordinary strength rating. The material component of this spell is a few hairs or a pinch of dung from a particularly strong animal — ape, bear, ox, etc.
