Rod of Rimefrost

Rod, rare (requires attunement)

This magic rod has 7 charges and regains all expended charges daily at dawn. As an action, you can expend 1 charge to cause one of the following effects:

• You create a nonliving object of ice that is no larger than a 5-foot cube within 30 feet of you. The object melts away after 1 hour.
• The ground in a 10-foot square centered on a point within 30 feet becomes slippery ice. The ice is difficult terrain and a creature that starts its turn there or enters the area for the first time on its turn must succeed on a DC 10 Dexterity saving throw or fall prone. The ice melts away after 1 minute.
• A Large or smaller creature within 30 feet you can see must make a DC 13 Dexterity saving throw or become encased in ice. The creature is restrained (escape DC 13) until the ice melts away after 1 minute.
