Act 3 offers some incredibly powerful weapons and items for a Vengeance Paladin. If you're using a two-handed weapon to maximize your damage, you could pick up Balduran's Giantslayer from the Dragon's Sanctum. This incredible sword doubles the bonus damage granted by your Strength Modifier whenever it connects, while also allowing you to increase in size (gaining temporary hitpoints, boosted damage, and advantage on Strength Checks and Saving Throws) once per short rest. If you're playing as a Githyanki, or respecced Lae'zel into a Vengeance Paladin, then the Silver Sword of the Astral Plane is also a good choice. It grants additional psychic damage on hit while also providing advantage on Intelligence, Wisdom, and Charisma Saving Throws. It also gives resistance to psychic damage, immunity to the "Charmed" status, and the special attack "Soulbreaker" to stun enemies.

At level one, an Oath of Vengeance Paladin is able to use "Inquisitor's Might." This allows them to grant bonus radiant damage to their weapon attacks, or those of an ally, as a bonus action. The bonus damage is equal to the Paladin's Charisma modifier.

The School of Necromancy grants the Wizard the abilities "Necromancy Savant" and "Grim Harvest," halving the cost of Scribing Necromancy Spells and allowing them to regain HP when they kill a creature with a leveled spell. The HP gained is equal to the spell slot used multiplied by two or multiplied by three if the spell was a Necromancy spell.

Updated on April 18th, 2024, by Thomas Hawkins: With the release of Patch 8 and the addition of Bladesinger to the Wizard Subclass list, new strategies and options have become available for this class. This update focuses on discussing the Bladesinging subclass and magic items that synergize well with its main playstyle.

This multiclass choice has little impact on a character's ability to use high-level spells. Because both classes are Prepared Spellcasters, and the ability to learn from scrolls only requires one level, a Cleric 11 Wizard 1 character will still be able to use Level 6 spells and have Level 6 spell slots unlocked.

Baldur's Gate 3 allows players to further customize their character via a subclass, selected either at character creation, at level 2 or at level 3, depending on the class. Warlocks choose their subclass during character creation since their subclass indicates what kind of being they made a pact with in exchange for their power. Be it a Fiend, Archfey, or Great Old One, their powers are sourced from dangerous creatures with ulterior motives.

Having access to Bladesong can be a huge boon to other spell-sword setups, like the Hexblade Warlock or even the Paladin, and since it doesn't rely on Intelligence, you could take the two-level dip to acquire Bladesong without needing to invest in that stat at all.

Players using the Spellsparkler can enhance their spell damage by picking up The Blast Pendant from a Petrified Drow near the Selunite Outpost. This allows them to convert lightning charges into bonus damage for their next spell. The Necklace of Elemental Augmentation will allow the Wizard to add their intelligence to the damage dealt by any Cantrip that deals Acid, Cold, Fire, Lightning, or Thunder damage, making it an excellent addition to an Evocation Wizard's kit. It can be found in the Inquisitor's Chambers at the Githyanki Creche. The Daredevil Gloves sold by the Merchant in the Creche are also helpful, providing a +1 bonus to spell attack rolls and converting ranged spell attacks into melee spell attacks when an enemy is standing next to the caster. This helps Wizards to dodge the disadvantage from casting spells while threatened.

There are a total of three BG3 Patrons (subclasses) Warlock 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 Warlock subclasses, you will gain more abilities that are unique to your subclass choice.

When it comes to multiclassing, Transmutation Wizards are uniquely suited to acting as non-combat support by crafting potions, using Rogue or Bard levels to gain medicine expertise and more efficiently double all dice skins Bg3 potion production. They can also make use of levels in Fighter or Cleric for access to medium and heavy armor, much like the other Wizard subclasses.

At level one, they also have the additional spell options "Faerie Fire" and "Sleep," allowing them to outline targets to grant advantage or just put their enemies to sleep. At level three, they can also choose "Phantasmal Force" and "Calm Emotions," letting them deal repeating psychic damage that will shift damage type to match the last attack that hit the target and allow them to immunize themselves and their allies from being charmed or frightened. Level five adds the options of "Plant Growth" and "Blink," letting them create difficult terrain and flicker out of reality after their turn to evade attacks (sometimes Fey Magic is fickle.)
