Conjure Animals 5e Guide

Conjure Animals in Practice

The spell lets you call forth beasts with a CR equal to half your caster level, rounded down. You cast at 3rd level, so that means up to CR 1. Cast at 7th, CR 2. That's the basic math, but the real decisions happen after you pick your CR option. I've run this spell in maybe two dozen campaigns across both DM and player sides, and there are a handful of things the PHB doesn't emphasize enough. Here's the core breakdown. At 3rd level you have three CR 1 choices: 1d4 + 1 Medium beasts, two Medium beasts of CR 1/2 or lower, four Tiny beasts of CR 1/4 or lower, or two Giant wasps. The elephant option only becomes available at 5th level caster, which is CR 2. Most people skip Tiny beasts outright because they have 5-foot reach and weak damage, but they're actually fine in tight corridors or indoor encounters where a Medium creature can't turn around. The summoning process works like this. You declare which option you want, roll the dice for HP immediately, and the creatures appear in spaces you choose within range. They act on your turn, not their own initiative count. This matters because if you need them to move first and then attack, you have to plan for that extra action cost on your end.

One thing people consistently get wrong is the timing of concentration checks. When a conjured beast takes damage and the spell ends, the beast simply vanishes and its remaining HP is lost. It doesn't stay at zero HP. This means area effects like Thunderwave or a single well-placed fireball can wipe out your entire summon depending on what you picked. A swarm of four Tiny beasts with 5 HP each will die to one gust of wind. Two elephants with 59 HP each will survive it just fine. Choose accordingly. I ran into a real problem last session with a level 5 druid who summoned four Tiny frogs because the encounter was indoors and the DM had placed pillars every fifteen feet. The frogs attacked with their bite attacks from cover behind pillars, but the DM ruled that two of the frogs were blocked by a pillar and couldn't reach the goblin. That cost us two turns of repositioning while the druid argued whether the frogs could squeeze through gaps. We settled on requiring the DM to roll for whether a Tiny creature could fit through any given gap, which took about ten minutes. The workaround I ended up using was having the player pick two Medium beasts instead, which cleared the room in one round without the spatial debate. At higher levels, specifically 7th and above when you can summon a CR 2 creature, the spell still hits a wall. There are only about six options at CR 2 that have reasonable stats. The mammoth is great but slow. The saber-toothed tiger has pounce, which is strong but requires a movement bonus to trigger. The elephant is the most reliable stat-wise but its trample isn't especially exciting in practice. You start seeing diminishing returns compared to just casting Spike Growth or calling down Lightning Bolt.

Another overlooked interaction is with the Extra Attack feature. If your conjured beast has Extra Attack and you give it the Attack action, it makes all its attacks. Some creatures at higher CRs have additional effects on their attacks, like the giant crocodile's Grapple on a hit. That grapple sets up a potential shove-prone combo for free. This is worth looking at when you're choosing between similar CR options. The spell's biggest flaw is also its most obvious one: it requires concentration. Any damage to you before the beast completes its action wastes the entire casting. At low levels, this happens constantly. A goblin with a shortbow can end your Conjure Animals in one hit. The average HP of a CR 1 beast is around 11 HP. That's two arrow hits from a proficient archer. If you're a wizard casting this defensively, you need to factor in that your AC is probably 12 to 14 without magical armor, making this a rough proposition. There's also the resource cost to consider. Each conjured beast uses up a spell slot, and you're trading a 3rd-level slot for what amounts to one or two extra attacks per round over ten minutes. In a five-round combat, that's four to eight additional attacks. Compare that to a Fireball at the same level, which deals 8d6 damage upfront and ends the encounter. The beast approach is more reliable against damage-resistant enemies but significantly slower against everything else.

For a concrete example of optimal usage: a level 5 druid fights six hobgoblins in open terrain. The druid casts Conjure Animals and picks two dire wolves with pounce. Both wolves move 60 feet and attack. One wolf kills a hobgoblin on its first hit. The second wolf misses but forces a concentration check on the hobgoblin captain, who fails and drops his action. The druid then casts Shillelagh on themselves. The two wolves kill three more hobgoblins in the next round. Combat ends in four rounds. Without the wolves, the druid would have taken damage and spent two rounds casting other spells with no guarantee of effect. If you're looking to use this spell regularly, the best approach is to memorize the CR 1 and CR 2 beast stat blocks rather than pulling them from the MM mid-combat. It cuts decision time from roughly two minutes to about thirty seconds per cast. The extra time saved adds up over a long session. There are better alternatives when you need something more reliable. Call Lightning at 3rd level does 4d10 on the first hit and 3d10 on subsequent turns, guaranteed damage that can't be dodged or resisted with saving throws. Dominate Beast at 4th level lets you control a single creature directly. Conjure Woodland Beings at 5th level summons fey, which often have different resistances and can Charmed instead of being commanded. The beast summoning route is situational but useful in the right context.

The bottom line is that Conjure Animals is a solid utility spell that scales reasonably well but has clear weaknesses. It's not a solve-everything tool. Use it when you expect a prolonged fight, when enemy resistances make damage spells less effective, or when you need body damage to soak up attacks. Otherwise, save the slot for something with more immediate impact.
