Improved Strength
By casting this spell, the wizard can empower a creature with superhuman strength. Unlike the 2nd‑level strength spell, improved strength allows the recipient of the spell to ignore race or class restrictions on his maximum Strength score, possibly reaching scores as high as 25. The exact amount of strength gained varies by the recipient’s class group:
Even if the recipient is not a warrior, he gains all the benefits of an exceptional Strength category; for example, if a thief with a Strength of 14 gained 7 points, he would possess a Strength of 18/76 for the duration of the spell. In addition to the attack and damage bonus, increased chance to open doors or bend bars, and increased carrying capacity, the spell recipient may temporarily gain the ability to throw boulders as a giant of equivalent Strength, as shown below:
When the spell ends, the recipient is struck by intense exhaustion; he can do nothing except rest for d3 full turns to recover his strength.
