Mass Polymorph 12 - Good effect, but other 9th level spells can't be replicated by simply having a bunch of lower level casters.
Meteor Swarm 19
Prismatic Wall 20 - "Wall of Force is 90% as effective" you say? PW isn't concentration, use both!

Time spent memorizing Prismatic Wall: 18 gold piecies.
Time spent adventuring to gain the extra levels to cast Prismatic Wall: 3,114 gold pieces.
Waggling your fingers for 6 seconds and saying a few words: 3 copper pieces.
Watching your enemy go blind, get incinerated, melt, fry from electricity, get poisoned, freeze, turn to stone and then have it's corpse fade onto another plane: Priceless.

Levels 10-17 are only worth 3114 gold? I've been allocating my money poorly.

Watching your enemy go blind, get incinerated, melt, fry from electricity, get poisoned, freeze, turn to stone and then have it's corpse fade onto another plane: Priceless.

This, just in case someone wanted to bring up Forcecage.
