Protection

Ones armour isn't strong enough to protect well against the foe ahead? Then Protection helps. Casting it, the spellcaster will be surrounded by a white aura, and their defensive values are increased against the foe for a limited time. However, this is only for one person. For the whole party, the Protect All spell is needed.

The purple potions fulfill the same purpose as the spell.

Trivia

 * In both Ultima Underworld, the spell is specialised into Missile Protection.
