Mass Might

When in serious need to overpower enemies, then Mass Might is to be cast. The Strength, Dexterity and Intelligence of all members of the caster's party (him- or herself included) will be boosted significantly for a limited time, giving them an enormous advantage in battle.

Despite it usefulness, it has no unwanted side-effects at all.

Trivia

 * The spell does the same thing as Silver Serpent Venom but without any of the ill effects!
