One use only. When an enemy spell has been cast, provided it was not cast with irresistible force. Teclis can read the Scroll of Hoeth instead of attempting to dispel the spell by using dispel dice. This automatically dispels the spell, no dice roll is required. In addition, immediately after the dispel has been resolved, both Teclis and the caster roll a D6; if Teclis scores higher, the caster immediately forgets the spell; otherwise, nothing else happens.
