I did change spells during the day, after Wight encounter I changed them when we went chase the supposed arsonist.<br/><br/>Also reason why Adrian can spontaneously cast summon monster is his magic item; Robes of Mystic Conjuration. It allows 3/day swap any spell from any level onto summon monster spell (doing so as part of casting action). Anyways forgot mention the spell which he sacrifices now from 4th level is Improved Invisibility (saving black tentacles for grappling fun if there is wights there).
