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

Description

Characteristics

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

Geomancer combat ability is by default used by 2 preset classes. The Wizard, which is a mage preset class, who uses Geomancer alongside Pyrokinetic combat ability and the Wayfarer, which is a survivor preset class, who uses Geomancer alongside Huntsman combat ability.

Geomancer on its own offers 3 support skills, 1 summon skill and 11 offensive skills. Craftable skills that include Geomancer offer 6 support (2 are incarnate infusions) and 4 offensive skills. Overall Geomancer offers 9 support skills, 15 offensive skills and 1 summon skill.

Geomancer ability on its own increases earth and poison damage from all sources by 5 % per each point invested. Note that in order to learn all Geomancer skills, the character needs 5 points in Geomancer (either by investment or by bonuses from items). Additionaly Geomancer increases all Physical Armour gained by 5 % per eeach point invested.

Earth and Poison Damage and Physical Armour Restoration bonus per point in Geomancer

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 Geomancer 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 Geomancer ability being spells 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 earth and poison damage done by Geomancer skills the most crucial elements are: level of the caster, Geomancer ability, intelligence attribute, high ground bonus and critical hit bonus.

Geomancer 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 earth or poison damage done.

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

Surfaces and Status Effects

Geomancer ability is focuses on mastering earth and poison. Therefore those who use it are most commonly capable of creating oil and poison surfaces as well as poison clouds and cursed poison surface. Note that these surfaces and clouds are flammable and explosive (the damaging aspect of these does not include their blessed counterparts). Also note that Undead will be healed by poison surfaces and clouds.

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

Traders

Following table shows all NPCs who are guaranteed to sell Geomancer 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. Out of these only Gareth and Almira may follow the Godwoken throughout the game on the Lady Vengeance, provided their demands are met.

Geomancer Skills

Ability Based

Following tables and sub-sections show Geomancer skills that can be learnt by character if they have enough point in Geomancer ability. All of these skills can be crafted by combining corresponding scroll with blank earth skillbook or high tier blank earth 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 Geomancer 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 Geomancer 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 Turn to Oil, character needs 1 point in both Geomancer and Polymorph combat abilities.

Source skillbooks are obtained whenever non-source Geomancer 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.

Runes

All equipment that has rune slots can be inserted with runes that will grant them additional properties. Most important rune for all who rely on Geomancer ability (in terms of damage and resistances bonuses provided) is the Rock Rune and the Venom Rune.

The Rock Rune increases earth damage when inserted into weapon. However it will increase File:Earth Resistance Icon.png Earth Resistance if inserted into armour instead. Lastly, if inserted into necklace or ring, it will increase Vitality by set amount. Mystical Rock Rune of any size provides 1 point bonus to either Warfare (if inserted into armour), Two-Handed (if inserted into weapon) and Geomancer (if inserted into any necklace or ring) alongside its base effect. Rock Rune of Power of any size will always provide bonus to Strength (depending on its size) whenever inserted into any equipment.

Venom Rune increases poison damage when inserted into weapon. Similarly to Rock Rune it will increase File:Poison Resistance Icon.png Poison Resistance if inserted into armour. And lastly, if inserted into necklace or ring, it will increase Accuracy. Mystical Venom Rune of any size provides 1 point bonus to either Summoning (if inserted into armour), Perseverance (if inserted into weapon) and Necromancer (if inserted into any necklace or ring) alongside its base effect. Venom Rune of Power of any size will always provide bonus to Finesse (depending on its size) whenever inserted into any equipment.
