Bestiary 4 | Monsters | Tiberolith | Special Abilities | Spell Trap
When a
tiberolith is targeted by a spell that allows
spell resistance and its
spell resistance fails to protect it against that spell, the spell instead becomes trapped in the
tiberolith's magical
runes. The
runes can only trap one spell at a time; if a second spell would become trapped, the first spell affects the
tiberolith normally (including allowing a saving throw, if appropriate) and the second spell is trapped. A trapped spell dissipates harmlessly after 24 hours.
