What are your favorite spell combos? Let me know!

Power Word: Kill outright kills the target, it doesn't deal damage, so it bypasses the protective effect of Polymorph.

Otto's irresistible dance and the grease spell were were always fun. But Death fog and wind wall basically turn combat into watching a gas chamber execution.

The Power Word Kill works because the wording is if the creature has less than 100hp, it dies. The spell doesn't reduce hp, it kills. DMs may rule differently as always.

Oh man, I cackled at the opening combo! Send em to the middle of nowhere, and once polymorph drops, the mental image of an enemies impotent rage just tickles me to no end!

You could use command spell "flee" on a target next to you. When they flee, you take attack of opportunity and if you have the war caster feat you can use booming blade. They can't stop because they're under the command spell.

The polymorph plus power word kill works because it doesn’t reduce you to zero hit points (which is a deprecate state where players become unconscious and monsters die) it kills your outright so you do not revert. Generally there’s little distinction between 0hp and dead but these are the edge cases.

If you want to really make a microwave busted you can use held actions to create a horrifying chain of reactions to prevent any chance of the enemy reacting. Just need the damage spell and wall of force to go off and reaction Darkness to block sight. This will keep even teleporters unable to get out (unless they can see through magical darkness or have Dimension Door which doesn't need to see the area you teleport to). It also makes it a whole team effort which is extra fun. Bonus points if the Darkness user can counter spell or another party member can counter spell or silence the enemy.

I had an Artificer who used Vortex Warp to drop a bad guy 70 feet out into Waterdeep's harbor. The guy was wearing heavy armor.

The one with the polymorph sperm whale is straight outta Hitch Hiker's Guide to the Galaxy.

a good combo I saw is basically Find Familiar+Dragon's Breath Imagine a firebreathing cat that'll do damage or a flying mini-dragon

Zyl, I love your videos. Your sass is top rate when it leaks through. I can't think of a story right now, I've been at an ER all day with my worst enemy (I hate him, I'm not a monster), and I just came home to this and actually laughed. Thank you. So, very much. Just thought of one when I was about to post. Haven't used it, but it should track. Otiluke's Freezing Sphere + Watery Sphere. "How long can you hold your breath, Mr. Bard?"

Polymorph + Enlarge Creature (needs two casters to maintain). Instant Kaiju. Alternatively, cast Enlarge Creature on a wildshaped Moon Druid for the same effect but even better, since they retain class abilities. ESPECIALLY if they also took a level in Barbarian and two in Fighter for Rage and Action Surge.

Polymorph the enemy into a slug then as a bard pour a salt shaker on it while casting vicious mockery

6:20 Ok, so quick correction here, Hex doesn't affect saves, it only gives disadvantage on ability checks. I know, it sucks

I haven't used it yet, but I realized the viability of a combination when looking up spells the one time I was building a Ranger. I call it "Mother Nature's Mincemeat Maker". Hail of Thorns + Conjure Barrage/Volley Cast Hail of Thorns first. Just don't use your second action to attack this turn. On your next turn, cast Conjure Barrage. I'll use a longbow for example, and assume +0 for the dex for simplicity. Hail of Thorns states that the attack comes from the ammunition upon a hit, and that it affects the next time you hit a creature with ranged weapon attack. It's not making magical ammunition. The spell takes effect once you hit. Conjure Barrage states that it creates a cone of *identical* weapons or ammunition that shoot forward and then disappear. So you fire off the Barrage. Everything in a 60 foot cone is hit, and takes 3d8 damage on a failed Dex save. Then Hail of Thorns comes into effect, since the Barrage is made of *identical* ammunition- and it copied the piece that has Hail of Thorns applied to it. Again, it isn't magical until it hits, so Conjure Barrage can fire it. Hail of Thorns says "the next time you hit a creature". Well, it doesn't specify which one, and Conjure Barrage's description heavily implies a simultaneous hit to all targets within range. Hail of Thorns states that the target hit takes the projectile's damage, 1D8 in this case, and then the target hit *and* all beings within 5 feet of them take 1D10 on another failed Dex save. Thanks to Conjure Barrage, we now have a cone of targets all set to suffer the same effect. TL;DR: Each enemy in the cone takes- Drumroll please... 3D8- from the Barrage 1D8- from the arrow 1D10- from the Hail of Thorns 1D10- from *all* targets within 5 Feet Hail of Thorns secondary damage A maximum of 42 damage per lone target in a 60 foot cone, which goes to a maximum of 122 (42 + 8 D10) damage for the center target if the targets are clustered together in a block of 9. All of this is Piercing Damage, and there is no attack roll- only Dex Saves. Alternatively, Conjure Volley ups the damage of Conjure Barrage with the same effect, to 8D8 rather than 3D8- in an 80 foot wide, 20 foot tall cylinder. Just don't expect your DM to allow you to use it. more than once if they're no fun.

Most of my favorite combos were already described, especially the hold and hammer variety. But there are a couple of old faves that weren't. One was a go to at low levels for me in 2nd/3.5 ed and might work in 5e is to cast hair growth followed by flame finger. Both cantrips so no real loss of battle power for later, doesn't do much damage but is REALLY distracting, awesome for a quick getaway. Another combo I loved for enemy mobs was web/fireball, and most DM's allowed the flames to catch fire so it works a bit like magical napalm. Absolute chaos typically ensues...ahhhh memories.

One me and my buddies came up with is Conjure Minor Elementals to summon Magma Mephits (summoner variant), then someone else casts elemental bane on the enemy, at which point the Mephits all cast heat metal, so at the very least (iirc) 8d8+8d6, ignoring resistance, and at max 40d8+40d6, as well as them all being able to barf lava as their subsequent action on their next turn. its a very very fun combo

Hex don't give disadvantahe on saving throws. Only skill checks so together with tasha hideous laughter it does absolutelly nothing.

Teleport an open bag of holding onto a visible enemy's head and have an Archer shoot the bag!

The thunderstep one would work only if you were a level 5 wizard and a level 3 artificer. But I'm definitely trying that out at some point.

hex gives disadvantage on checks not saves

I thought people used Polymorph and power word kill to kill enemies like Terasque? I could be wrong but you Polymorph your enemies or BBEG into like a chicken or something and then power word kill it

Hex does not affect saving throws

An even better combo for the cheese grater is repelling blast and grasp of hadar
