Din leveled up, so I'm going to unlock the Spell of Summer:

[list][*]Spell of Summer - Din targets a patch of ground with the Rod, changing the localized season to summer. This creates desert-like heat in the area for low heat damage, and may cause flammables and explosives to spontaneously combust. The effect can also dry out objects within, or make enemies weaker to flame attacks. Also has a temporary, mild blinding effect.[/list]

One more season to go before the Rod is complete.
