Aerotheurge is a combat ability, that utilises magic known as aerotheurgy, and is essential for learning and casting Aerotheurge skills as well as crucial determining factor of the effectiveness of air based weapons and ammunition in Divinity: Original Sin 2.

Description

Characteristics

Aerotheurge combat ability focuses on dealing air damage, which is resisted by File:Magic Armour Icon.png Magic Armour and File:Air Resistance Icon.png Air Resistance. Magic Armour prevents negative status effects from affecting characters whereas Air Resistance directly lowers air damage done. The reduction is based on percentage, therefore character with + 10 % air resistance will receive 10 % less air damage.

Aerotheurge combat ability is by default used by 2 preset classes. The Battlemage, which is a warrior preset class, who uses Aerotheurge alongside Warfare combat ability and the Enchanter, which is a mage preset class, who uses Aerotheurge alongside Hydrosophist combat ability.

Aerotheurge on its own offers 3 support skills, 1 utility skill, 3 mobility skills and 8 offensive skills. Craftable skills that include Aerotheurge offer 9 support (2 are incarnate infusions) and 2 offensive skills as well as 1 utility skill. Overall Aerotheurge offers 12 support skills, 10 offensive skills, 3 mobility skills and 2 utility skill.

Aerotheurge ability on its own increases air damage from all sources by 5 % per each point invested. Note that in order to learn all Aerotheurge skills, the character needs 5 points in Aerotheurge (either by investment or by bonuses from items).

Air Damage bonus per point in Aerotheurge

Level	Damage Boost (%)	Level	Damage Boost (%)
1	5	2	10
3	15	4	20
5	25	6	30
7	35	8	40
9	45	10	50

Damage of Aerotheurge Skills

Damage in Divinity: Original Sin 2 is calculated through this exact formula: Damage = (Base Damage) x (1 + Elemental Bonus%) x (1 + Attribute Bonus% + Weapon Skill Bonus% + Misc Bonuses% [if attack]) x (1 + High Ground Bonus% + Crit Bonus%) x ( 1 + Misc Bonus% [if spell])

Due to skills under Aerotheurge ability being skills they all use the following formula for damage: (Base Damage) x (1 + Elemental Bonus%) x (1 + Attribute Bonus% + Weapon Skill Bonus %) x (1 + High Ground Bonus% + Crit Bonus%) x ( 1 + Misc Bonus %). Additionaly they cannot be cast if caster is affected by File:Silenced.png Silenced and File:Enraged.png Enraged status effects.

Simply put for the air damage done by Aerotheurge skills the most crucial elements are: level of the caster, Aerotheurge ability, intelligence attribute, high ground bonus and critical hit bonus.

Aerotheurge skills DO NOT rely on the base damage done by weapons. However weapons affect damage done if they provide boost to any of the above mentioned elements that affect air damage done.

Therefore in order to boost damage done by Aerotheurge skills it is crucial to increase: Level, Aerotheurge, Intelligence, High Ground Bonus, Critical Hit Bonus. If possible it is wise to lower the air resistance of enemies. Note that bonus to damage provided by Intelligence is smaller than bonus provided by Aerotheurge ability.

Surfaces and Status Effects

Aerotheurge ability is focuses on mastering air. Therefore those who use it are most commonly capable of creating electrified surfaces. These can be made from any surface (and cloud) that contains either blood or water, it matters not whether it is blessed or cursed. Electrifying any of these will create electrified surface/cloud.

Aerotheurge skills are also capable of causing a variety of status effects. Below is a table listing all effects caused by Aerotheurge combat ability skills.

Traders

Following table shows all NPCs who are guaranteed to sell Aerotheurge skillbooks, with their location and coordinates in the right column, from them. The location shown in the table (and the coordinates) are only for the initial location the NPC is in. Note that some of these may have other skillbooks and goods to sell. Almira may follow the Godwoken on Lady Vengeance if her demands are met. Also note that Lizard Dreamer requires a persuasion check to be passed in order to speak with him, otherwise he (and the whole encampment) will turn hostile.

Aerotheurge Skills

Ability Based

Following tables and sub-sections show Aerotheurge skills that can be learnt by character if they have enough point in Aerotheurge ability. All of these skills can be crafted by combining corresponding scroll with blank air skillbook or high tier blank air skillbook. Note that not all skills have craftable scrolls. In base game (without cheats) skills from 9 level onward (Adept, Expert and Master tiers) can be gained only after escaping Reaper's Eye island.

Each skill belongs to a tier that is determined through characters level that determines whether it can be found and purchased and requires certain level in Aerotheurge ability in order to memorise the skill. Higher Tier skills may require more memory in order to use them in combat, this especially applies to skills that require Source in order to cast them.

Craftable

Following skillbooks are classified as craftable for they can be obtained only by crafting them. They cannot be bought from any trader in the game. However it is possible to get them as quest reward or find them as random loot.

Base skillbooks are obtained whenever non-source Aerotheurge skillbook is combined with another non-source skillbook. Resulting skillbook will be a mix of both skillbooks and will require investment in both combat abilities under which the skillbooks belong. Example: In order to learn and cast Healing Tears, character needs 1 point in both Aerotheurge and Polymorph combat abilities.

Source skillbooks are obtained whenever non-source Aerotheurge skillbook is combined with source skillbook and vice versa. One way or another there has to be source skillbook involved in crafting otherwise the resulting book will be non-source skillbook. Like base craftable skillbooks these also cannot be bought from traders in game.

Lastly the Frost Rune grants File:Air Resistance Icon.png Air Resistance when inserted into armour. If the base Thunder Rune of any size is put into rune frame it will gain additional effects.

Mystical Thunder Rune of any size provides 1 point bonus to either Scoundrel (if inserted into armour), Dual Wielding (if inserted into weapon) and Aerotheurge (if inserted into any necklace or ring) alongside its base effect.

Thunder Rune of Power of any size will always provide bonus to Finesse (depending on its size) whenever inserted into any equipment.

Notes

• The adept Aerotheurge skill Apportation is not sold by traders and can be only acquired by making a scroll and crafting a skillbook out of it. Aerotheurge is therefore the only combat ability that has by default only 3 Adept (level 9) skills. It is unknown whether this is a bug or intention from the developers.
