Having returned from a recent journey to Middle Earth, I suggest adding two new spells to help groups assemble go more quickly.
Improved Teleport: This spell works exactly like Teleport but allows all party members within 5 meters to travel with the caster. In essence, it combines the features of Greater Teleport with the destination list of Teleport.
Word of Summons: This spell allows the caster to summon one party member to his or her current position. Word of Summons may only be cast in a place where a hireling contact may be used. Word of Summons essentially works like Summoning Horns in Middle Earth. The restriction related to hireling contract use prevents any mischief. I suggest pairing this spell with a new setting, [] Always ignore Word of Summons.
I suggest making both spells readily available as scrolls and recharging magic items for obvious reasons.
Thank you for your consideration.
