Ring of enduring arcana

Rings of enduring arcana render a spellcaster's spells more resistant to dispelling.

Appearance
A ring of enduring arcana appears as a fine latticework of gold and mithral that covers most of the length of the wearer's finger, with a joint in the middle to allow movement. It seems to shift and flow whenever the wearer casts a spell.

Activation
A ring of enduring arcana is permanently active for as long as it is worn. However, it does require 24 hours to acclimate to the wearer, starting when it is donned.
