The runic staff of power.
It was a staff that weighed no more than a few pounds and was as smooth as black jade. The top of the staff was embedded with a mysterious sparkling gem, and complicated arcane runes were engraved on it.
The 'runic magic staff' was another form of a magic staff. It could allow the caster to consume the spell slots of a spell-level spell to cast the spells engraved in the runic magic staff, which was equivalent to expanding the limit of the spell slot of the wizard.
For example, the strength runic magic staff in Zhao Xu's hands that was worth around 60000 gold coins could use up spell slots to cast ice pick, inextinguishable flame, fireball, invalidate barrier, hold monsters, levitate, Lightning Arrow, magic missile, ray of enfeeblement, force field wall, and other spells.
It was just that Zhao Xu had the two great skills of being a multi-talented spellcaster and bizarre forethought, so it wasn't as significant as the other spell casters.
