You're standing in the middle of a blood-soaked campsite, your party is hanging by a thread, and you're staring at your Cleric’s spellbook. You see Aid. It looks great—increasing hit point maximums is a literal lifesaver in Baldur’s Gate 3. But then the anxiety kicks in. You’re low on spell slots. You wonder, is aid a ritual spell in BG3, or are you about to burn a precious resource that you’ll desperately need when that Owlbear decides to turn you into a snack?
Let’s get the direct answer out of the way immediately: No. Aid is not a ritual spell in BG3.
If you click it expecting it to be free of charge outside of combat, you’re going to be disappointed. It costs a Level 2 spell slot (at minimum). It doesn't have that little green "Ritual" tag that spells like Longstrider or Speak with Animals carry. You cast it, the slot vanishes, and you’re left with the consequences. But honestly? It’s still one of the best spells in the game, even if Larian didn't give it the ritual treatment.
Why the Confusion Happens
It’s easy to see why people get mixed up. In the tabletop version of Dungeons & Dragons 5e, players are constantly looking for ways to preserve resources. Because Aid lasts until a Long Rest, it feels like it should be a ritual. It’s a "buff it and forget it" kind of deal.
In Baldur’s Gate 3, we have a handful of spells that are rituals. Longstrider is the big one. Everyone casts Longstrider on the whole party every morning because it’s free movement. Since Aid also lasts until the next time you put your head on a pillow, players naturally lump them together.
But they aren't the same. Not even close.
Ritual spells in BG3 generally provide utility, movement, or information. Aid provides raw, cold, hard survivability. It increases your maximum HP. It heals you for that amount. It scales. If Larian made Aid a ritual, the game’s difficulty would plummet because every single player would have a massive HP cushion for zero cost. That’s just not how the math of the Sword Coast works.

How Aid Actually Works (And Why It’s Still Worth the Slot)
Don't let the lack of a ritual tag scare you off.
When you cast Aid at Level 2, you and your nearby allies gain 5 extra maximum hit points. That might sound like a pittance when you're staring down a Boss with 400 HP, but it adds up. It’s not "temporary hit points" either. That is a crucial distinction. Temporary HP (like from the False Life spell or the Rally maneuver) doesn't stack. If you have 5 temp HP and someone gives you 10, you have 10, not 15.
Aid actually increases the ceiling. It stacks with everything.
The Upcasting Secret
The real power comes from upcasting. This is where the spell goes from "fine" to "essential." For every spell level above 2nd, you get an additional 5 HP.
- Level 3 slot: +10 HP
- Level 4 slot: +15 HP
- Level 5 slot: +20 HP
- Level 6 slot: +25 HP
Think about that. At Level 11 or 12, casting Aid at the 6th level gives everyone in your active party (and your summons!) an extra 25 HP. For a party of four, that’s 100 extra HP the enemy has to chew through. If you have a bunch of ghouls or an elemental following you around? They get it too. It turns a fragile squad into a tanky legion.
The Camp Follower "Cheat"
Since is aid a ritual spell in BG3 is a resounding "no," you might be feeling protective of Shadowheart’s spell slots. I get it. You need those for Spirit Guardians or Guiding Bolt.

Here is the pro tip that seasoned Honor Mode players use: The Camp Cleric.
You can recruit a Hireling from Withers or leave a companion like Seluné-path Shadowheart at camp. Switch to them, put them in your party temporarily, and have them cast Aid using their highest spell slot on your main adventuring party. Then, dismiss them and pick up your preferred companion.
The buff stays.
The spell slot used was the Camp Cleric's, not your active party’s. You get all the benefits of a massive HP boost without the "cost" of a spell slot during your actual exploration. It feels a bit like gaming the system, but in the brutal world of Act 3, you take every advantage you can get.
Strategic Nuance: Combat vs. Preparation
Most people cast Aid immediately after a Long Rest. That’s the smart move. However, there is a niche use for it in the middle of a fight.
Because Aid increases your current HP along with your maximum, it acts as a multi-target heal. If three of your teammates are downed (at 0 HP), casting Aid will bring all of them back to life with whatever HP the spell provides. It’s like a massive, area-of-effect Healing Word that also buffs them.

Is it efficient? Usually no. A Level 2 slot for 5 HP is a desperate move. But in a pinch, it can save a run from a Total Party Kill.
Comparing Aid to Other Buffs
You might be wondering if you should use Heroism or Protection from Evil and Good instead.
Honestly, Aid is better for general use because it doesn't require Concentration. That is the gold standard for spells in BG3. You cast it once, and it’s done. You can still concentrate on Haste or Bless or Slow while enjoying the extra HP from Aid.
- False Life: Only affects the caster. Doesn't stack with other temp HP.
- Heroes' Feast: This is the Level 6 powerhouse. It provides 12 HP, immunity to poison/frightened, and advantage on Wisdom saves. The crazy thing? Heroes' Feast and Aid stack.
If you use a 6th-level Aid and a Heroes' Feast, your party is walking around with nearly 40 extra HP each. Your Wizard will suddenly have the health bar of a Barbarian. It's glorious.
The Verdict on Your Spellbook
While we’ve established that Aid isn't a ritual, it occupies a unique space in the game's balance. It's a tax on your resources that pays out dividends in survivability.
If you are playing on Balanced or Explorer, you can probably ignore it and just smash your way through. If you are playing on Tactician or Honor Mode, ignoring Aid is a death wish. Those extra 10 or 15 points are often the exact margin between surviving a Dragon’s Breath or looking at a "Game Over" screen.
So, don't wait for a "Ritual" tag that isn't coming. Use your slots. Or better yet, use Withers to get a dedicated buff-bot and keep your main characters ready for the heavy hitting.
Actionable Optimization Steps
To get the most out of your HP management in Baldur's Gate 3, follow this routine after every Long Rest:
- Check your slots: Determine if you have a spare Level 3 or 4 slot on your Cleric or Paladin.
- Summon first: If you use Find Familiar, Spiritual Weapon, or Conjure Woodland Being, cast those before you cast Aid. The spell hits everyone in the radius, including summons, making them significantly harder for enemies to one-shot.
- Group up: Bring your party close together in the center of camp. The radius is decent, but you don't want to miss the stray Astarion lurking in the shadows.
- Upcast aggressively: If you have a Level 4 slot and a Level 2 slot, and you aren't sure which to use, go with the Level 4. The 15 HP boost is a 200% improvement over the base level and scales perfectly with the increasing damage of enemies in Acts 2 and 3.
- Identify the "No Ritual" trap: Always hover over your spells. If you don't see the "Ritual" keyword in the tooltip, casting it will consume a slot regardless of whether you are in turn-based mode or just hanging out at camp. Don't get caught empty-handed before a big fight.
