Most Interesting / Effective Spell Combos

I am curious to hear about any interesting and creative ways to combine spell effects that any of you have used/observed.

For example, I was playing a pacifist bard in a group of low-level pcs. I tried to get the party to avoid any fight possible (not easy) and avoid killing when we did have to fight.

We came across a room full of goblins that we needed to clear out. The party wizard and myself came up with an idea. One of us cast Dancing Lights and formed it into a humanoid shape in the midst of the goblins. The other cast Ghost Sounds to give it a bit of voice. Needless to say, many of the goblins bolted for the nearest escape. It made the encounter a lot easier, and we didn't have to kill all of the goblins. And of course, bonus xp for creativity.

So does anyone have a fun little story like that? Or even if it is something as utilitarian as Vanish/Doom from FFVI, please share.

Not so much an interesting combo, but...

Had a group going up against a very young dragon (wyrmling?). It managed to put the barbarian, rogue, and wizard to sleep with its breath attack, leaving just the wizard. The cleric started freaking out, looked at his spell list, and a light went off. The barbarian was doused with several gallons of water, waking him up. He proceeded to jump up on his feet, narrowly avoiding death from the AoO, then proceeded to Triple-20 the dragon.

We're still debating who the true hero of that battle was.

Here's quite a combo: Create Water and Continual Flame. The group was imprisoned and without most of their equipment. The cleric decided to do a little trick on the jailers (forget what race). He filled up a bowl with water, then cast a green flame on it (DM ruled color didn't matter). After getting the attention of the guards, who wondered where they had gotten alchemist's fire, proceeded to down the concoction. DM said +20 or something to intimidate. The cleric put on quite a show about 8 hours later. ;)

Not particularly clever, insightful, or anything like that. It just happens to be a combo that caught my group's attention one session.

Note: This is with Castles & Cruades.

The party had finally come across the "boss fight" with a villain and numerous of her minions. I was stoked, this was going to be a great, massive, epic battle.

The party wizard had won initiative on the opening round and started out by casting Time Stop (he had justed turned level 17 after the last session and only now gained access to 9th level spells). Rolling his d4, it came up 4. So, add +1 and the duration was 5 rounds.

He then cast 3 chain lightnings and I believe it was a delayed blast fireball (ensuring the BBEG was included in all of the effects). When Time Stop expired, the fireworks began and the ENTIRE opposing group was laid to waste in an impressive light show. The wizard simply gave a slight grin.

The rest of the party decided they'd be nice to the wizard from there on out.

Oldie but a goodie:

Grease + Slow. They spend their partial action standing up.

That spell that makes spikes grow on wood (Brambles? I forget) + Levitate + A log or Portable Battering Ram.

Bring log into dungeon. Cast levitate on it. Levitate should make it weightless (think item in zero-g). Cast the spike spell on it. When you see an enemy, get several PCs to shove it down the hall at the enemies.

Invisibility + Open/Close. Spot an enemy, then go back to a safe room and cast Invisibility on the door. Go back to the enemy, get them to chase you. Run into the safe room, cast open/close (and Arcane lock if you got it). Even better if you've got spells that can go through thin wood (since you have line of sight, you just need line of effect).

The least clever thing ever, but Web followed by Burning Hands (or Fireball, or Alchemist's Fire, in a pinch).

I've been particularly happy with Otiluke's Resilient Sphere and Dimension Door. Sometimes the sphere can be used on an enemy to take them out of the fight, but they get a save, and often that isn't as helpful anyway. What I've done is attract the enemy's attention, get it attacking me (especially if it's low intelligence), then cast the sphere on myself, let it batter away futilely another round or two, then dimension door out. You can enhance this by going invisible, then laying down an illusion of yourself before dimension dooring out of the sphere.

Oldies but goodies

Targetted Dispel + Shatter: use on any pesky magic item (or just Shatter to watch fighters and rogues cry when their potions go crash)

Revenance + Revifiy: If you can't get to a fallen comrade in 1 round to cast revivify use a revenance as it brings them back to life for a short amount of time (in combat ready condition) then they die again and by then you should be ready to Revivify! No more pesky Raise Deads and negative levels!
