If the user meets all the requirements noted above, and her caster level is at least equal to the spell’s caster level, she can automatically activate the spell without a check. If she meets all three requirements but her own caster level is lower than the scroll spell’s caster level, then she has to make a caster level check (DC = scroll’s caster level + 1) to cast the spell successfully. If she fails, she must make a DC 5 Wisdom check to avoid a mishap (see Scroll Mishaps, below). A natural roll of 1 always fails, whatever the modifiers.
Determine Effect: A spell successfully activated from a scroll works exactly like a spell prepared and cast the normal way. Assume the scroll spell’s caster level is always the minimum level required to cast the spell for the character who scribed the scroll (usually twice the spell’s level, minus 1), unless the caster specifically desires otherwise.
The writing for an activated spell disappears from the scroll.
Scroll Mishaps: When a mishap occurs, the spell on the scroll has a reversed or harmful effect. Possible mishaps are given below.
• A surge of uncontrolled magical energy deals 1d6 points of damage per spell level to the scroll user.
• Spell strikes the scroll user or an ally instead of the intended target, or a random target nearby if the scroll user was the intended recipient.
• Spell takes effect at some random location within spell range.
• Spell’s effect on the target is contrary to the spell’s normal effect.
• The scroll user suffers some minor but bizarre effect related to the spell in some way. Most such effects should last only as long as the original spell’s duration, or 2d10 minutes for instantaneous spells.
• Some innocuous item or items appear in the spell’s area.
• Spell has delayed effect. Sometime within the next 1d12 hours, the spell activates. If the scroll user was the intended recipient, the spell takes effect normally. If the user was not the intended recipient, the spell goes off in the general direction of the original recipient or target, up to the spell’s maximum range, if the target has moved away.
