The Circle of Spores Druid gains a "Halo of Spores" at level two. This allows them to deal necrotic damage (1d4) to a target within 6m as a reaction each turn. They also gain "Symbiotic Entity" at level two, letting them spend a Wildshape charge as an action to gain 4 temporary HP per Druid level. "Symbiotic Entity" also allows them to deal an extra 1d6 necrotic damage while those temporary hit points remain and doubles the damage dealt by "Halo of Spores." They also gain the "Bone Chill" Cantrip as an extra way to deal necrotic damage while nullifying a foe's ability to heal themselves.

The max level in Baldur's Gate 3 is Level 12, and most of the time, each level you gain will grant something new for your Druid build. On character creation you gain the basics for the Druid class, then steadily gain Feat Choices, new spells and abilities, subclass features, and increase your Proficiency Bonus.

There are a total of seven BG3 Circles (subclasses) Druid players can try out, each of which focuses on different aspects of the class, and offers a selection of unique skills, proficiencies, and other features. As you level up in one of these BG3 Druid subclasses, you will gain more abilities that are unique to your subclass choice.

When Multiclassing with the Circle of the Moon, it is important to understand that a lot of features won't work while in Wildshape. Generally speaking, Class Actions that require the player to spend an action or bonus action will be unavailable while in Wildshape, but passive abilities will. Thus, abilities like Unarmored Defense (from Barbarian and Monk) will function in Wildshape (as long as the character wasn't wearing armor when they entered Wildshape), as will the Improved Critical ability from Champion Fighter. The War Cleric Extra Attack also works while Wildshaped, which can be useful. Players can also take levels in Barbarian and enter a Rage before using Wildshape to benefit from Rage while in Wildshape.

Most of Baldur's Gate 3 's classes only have three subclasses to choose from, but clerics are able to choose from seven options. The domains of Life, Light, Trickery, Knowledge, Nature, Tempest, and War All Dice Skins Bg3 offer a cleric different abilities. A Cleric chooses their subclass at level one to reflect the power of their god's domain. What subclass they can choose is limited by the domains made available by their chosen Deity (which is also selected at level one).

Going back on their word or engaging in cruelty will cause a Paladin who swore the Oath of Devotion to become an Oathbreaker. This makes it an especially tricky subclass to maintain when playing as the "Dark Urge" origin, whose bloodthirst is hard to control and can lead to accidents. Another early example of somewhere this Oath can be broken is during the encounter with Damays and Nemissa in Act One, with Lae'zel in a cage, as choosing to attack Damays and Nemissa will immediately break the Oath of Devotion​​​​​​.

Players can get excellent results by mixing in the Acid Damage equipment, beginning with the Caustic Band sold in the Myconid Colony in Act 1, which adds 2 Acid damage to all weapon damage dealt by the wearer. This is a small but helpful addition that becomes much more dangerous when paired with the Ichorous Gloves (Act 2, Stashed in the Storeroom at The Waning Moon) to apply the Noxious Fumes condition. This condition causes creatures within 3m of the target to take 1d4 acid damage. Add Varsh Ko'kuu's Boots (Act 1, Githyanki Creche) to gain resistance to Acid and immunity to acid surfaces.

Oath of the Ancients Paladins are defenders of Life and Nature first and foremost, similar in some respects to Druids. They gain Healing Radiance as their first Channel Oath ability, allowing them to perform an AOE Heal centered on themselves which pulses a second time at the start of their next turn. This can be tremendously useful when fighting in melee alongside other party members.

In addition to everything you unlock while leveling as a Cleric, your Subclass also determines what you unlock at certain levels. As a Cleric, you can select a subclass at Level 1, in the character creation menu.

There are a total of seven BG3 Domains (subclasses) Cleric players can try out, each of which focuses on different aspects of the class, and offers a selection of unique skills, proficiencies, and other features. As you level up in one of these BG3 Cleric subclasses, you will gain more abilities that are unique to your subclass choice.

The Circle of Spores Druid has a tremendous amount of synergy with the Necromancy School available to Wizards, and taking six levels of Wizard will allow them to create a much greater range of undead minions to aid them in battle. This has the added benefit of granting them access to the entire Wizard spell list thanks to both classes being full casters, though a character will need to invest in intelligence to make full use of the Wizard spells. The Circle of Spores also synergizes well with the Monk, allowing players to brawl in melee and improve their AC using their Wisdom, which will already be pretty high since it's the Druid's spellcasting stat. Fighter and Ranger are both excellent multiclass choices too, offering Extra Attack at level 5 to dish out more Necrotic Damage while using Symbiotic Entity. Ranger synergizes slightly better due to also providing additional spell slots. (Rangers are half-casters so half of the Ranger Level, rounded down, is added to the effective caster level when multiclassing.)
