PnP description:
Transmutation
Level: Sor/Wiz 6
Components: V, S, M
Casting Time: 1 action
Range: Personal
Target: The character
Duration: 1 round/level
The character gains 1d6 temporary hit points per caster level,
a +4 natural armor bonus to AC, a +2d4 Strength enhancement bonus,
a +2d4 Dexterity enhancement bonus,
a +1 base attack bonus per two caster levels
(which may give the character an extra attack),
a +5 competence bonus on Fortitude saves,
and proficiency with all simple and martial weapons.
The character attacks opponents with melee or ranged weapons if the character
can, even resorting to unarmed attacks if that’s all the character can do.
The character can’t cast spells, even from magic items.
Material Component: A potion of Strength,
which the character drinks (and whose effects are subsumed by the spell effects).
