D&D 5E Twinned Spell + Extended Spell + Conjure X build?

[faria]

I realized a few things:
1) The Conjure X spells don't have a range of Self, therefore they can be Twinned Spelled with Sorcery points. Most also have a casting time of 1 minute, so they would benefit from Extended Spell.
2) The way Twinned Spell is worded, you only need to spend Sorcery Points equal to the level of the spell, NOT the slot used to cast it. For example, to Twin Conjure Animals, you'd need to spend 3 Sorcery Points because it's a 3rd level spell, even when casting it with a 7th level slot for the extra animals. (Note: Conjure Animals has a casting time of 1 action, not 1 minute, so it wouldn't benefit from Extended Spell! To benefit from both points 1 and 2, pick a different Conjure X spell.)
3) For just a couple more Sorcery Points, you can keep those summons out for hours. Even all day............

So, what's the best build for this?

Conjuration Wizards can't lose concentration from damage at level 10 and can even give all their summons temp HP at level 14. But they don't have access to a lot of Conjure X spells. The lowest would be Conjure Minor Elementals. They could cast all the Conjure X spells at level 17 with Wish, but only once a day... With Extended Spell though, maybe you'd only need to cast it once per day... Let's see!

If we go Conjuration Wizard 17/Sorcerer 3, we can use Wish to cast Conjure Animals and use all 3 Sorcery Points for Twinned Spell. We would not benefit from Extended Spell though. They would benefit from the level 14 Conj Wizard temp HP ability. We would have access to 9th level spells in case we decide to Wish for something else... Kinda defeats the point of this combo though.

If we go Conjuration Wizard 14/Sorcerer 6, we can cast Conjure Minor Elementals and use 4 Sorcery Points for Twinned Spell. We would have 2 Sorcery Points left over for Extended Spell, making them last 1*2*2=4 hours. They would benefit from the level 14 Conj Wizard temp HP ability. We would have access to 7th level spells. Seems like this could work, but I think we can do better.

If we go Conjuration Wizard 10/Sorcerer 10, we can cast Conjure Minor Elementals and use 4 Sorcery Points for Twinned Spell. We would have 6 Sorcery Points left over for Extended Spell, making them last 1*2*2*2*2=16 hours and still have 2 Sorcery Points left over. If we wanted to cast Conjure Elementals instead, we could use 5 Sorcery Points for Twinned Spell. We would have 5 Sorcery Points left over for Extended Spell, making them last 1*2*2*2*2=16 hours and still have 1 Sorcery Point left over.

Since we have 1 Sorcery Point left over above, why not go Conjuration Wizard 11/Sorcerer 9 for access to 6th level spells. This seems like the sweet spot to me. Yes, we lose access to the level 14 Conj Wizard temp HP ability, but we make up for it by casting Conjure Elemental instead of the Minor version. Among other things, it also guarantees no DM screwing us with the other Conjure X spells where THEY choose what shows up. Even without Extended Spell, we'd have multiple level 5+ slots to cast Conjure Elemental with as a straight Conjuration Wizard 11. At level 13 we can extend the spell to 4 hours. At level 16 we have access to Twinned Spell and can have 2 Elementals out. At level 17+ we can have 2 elementals out at once that eventually last all day! If you really want to delay the 11th level of Wizard, you can multiclass a level earlier (I would still wait until Wiz 10 before multiclassing) and get all your Sorcerer goodies a level earlier. Might actually be worth it here. Level 6 spells aren't that important for this build...

Thoughts?

All this build needs to have 2 elementals all day long is Conjuration Wizard 10/Sorcerer 9. So there's 1 extra level left... I'm still not sure if it's really worth taking that 11th level of Wizard for this...

I think 1 level of Paladin or Cleric would be better. Heal spells, Heavy Armor, a few other goodies... I'm actually leaning towards Paladin for the Protection Fighting Style, to keep your elementals up longer (could even take Mounted Combatant and ride one of the elementals). You'd need 13 STR, CHR, and INT. What sucks is that to get Heavy Armor, we'd have to start with Paladin at level 1.

Choices...

But Twinned Spell requires the spells to target a single creature, which Conjure X does not do. It targets a space where the elemental appears.

 

[mellored]

you can not use 2 metamagics on the same spell.

Because of the reasons above this doesn't work. Sorry :/

 

[kalani]

Not only does this not work but you also are misinformed as to how spell levels work. When you upcast a spell, it becomes a spell of its new level. Using your example, conjure animals in a 7th level slot is treated as a 7th level pull for all game effects with one singular exception - Tiamat (Rise of Tiamat)can still ignore its effects due to the wording of her ability

The only Sorceror that's any good at Conjuration is the Favored Soul because it has access to the rare conjuration spells the Sorceror has access to (Teleporting/Planeshifting, Gate and Wish that is it), plus the conjuration spells that the cleric has (its an even better Necromancer thanks to Cleric Spells).


A Favoured Soul Conjurer can take Spiritual Weapon, Spirit Guardians, Guardian of Faith, Conjure Celestial, and use Extend Spell on them, Extend Spell by itself is still good, its, like casting the spell again after the first time, but at a much cheaper cost then twin spell.

So you can extend a ninth level Conjure Celestial to Double the time, its like casting it twice, at the cost of 1 Sorcery Point. And unlike most Conjurations Guardians of Faith do not require consentration and last 8 hours (16 with extend spell).

Another cool thing is you can take deathward too and cast it on anything you conjure that can be attacked, like Conjure Celestials.

Also an interesting possiblity, Sorceror 3/Druid Circle of the Sheppard, for extend spell on the Druids summonings.
