Intelligence

Intelligence is one of the six basic stats of DDO.

Intelligence (INT)

Intelligence determines how well your Player Character learns and reasons. This ability is important for Wizards, Artificers and Alchemists as it affects how many spell points they have, how hard their spells are to resist, and how powerful their spells can be. It's also important for any character who wants to have a wide assortment of skills.

You apply your Player Character’s Intelligence modifier to:

• Disable Device, Repair, Search, and Spellcraft skill checks. These are the skills that have Intelligence as their key ability.
• The amount of bonus spell points you gain as a Wizard, Artificer or Alchemist.
• The number of skill points gained each level.
• The Spell Difficulty Class (DC) for Wizard, Artificer and Alchemist spells.
• The Insightful Reflexes Feat allows Intelligence to be used for all Reflex Save rolls, instead of Dexterity.
• The Alchemist bonus feats Liquid Courage and Tough Tincture allow Intelligence to be used for Will or Fortitude saves respectively.
• Harper Know the Angles will add 1/2 your intelligence modifier to your damage rolls and the Difficulty Class(DC) of your Tactical feats.
• Mechanic Tanglefoot, Thunderstone, Ooze Flask, and Time Bomb use Int Modifier for the Difficulty Class(DC).
• Assassin Poison Strikes, Shadow Dagger and Assassinate use Int Modifier for the Difficulty Class(DC).
• Arcanotechnician Arcane Empowerment uses Int Modifier for the Difficulty Class(DC).
• Vile Chemist Tier 4: Simple Thrown Mastery allows Int modifier to improve the effects of the Simple Thrown Expertise feat.

Intelligence for Attack and Damage

You can apply your Intelligence modifier to your attack rolls and/or damage rolls through the use of:

• Harper Tier 1: Strategic Combat I (attack rolls, no shield bashes) and Tier 3: Strategic Combat II (damage rolls, no shield bashes)
• Eldritch Knight (Wizard) Tier 3 enhancement: Eldritch Accuracy (attack rolls only)
• Swashbuckler Tier 3 enhancement: Different Tack (damage rolls only)
• Mechanic Core 3 enhancement: Targeting Sights (damage rolls with Crossbows and thrown weapons only)
• Battalion Brew Alchemist bonus feat (attack rolls with Simple weapons only)
• Some named items, for example Stave of the Seer

Feat Prerequisites and Skill Points

The following Feats have a minimum Intelligence Requirement:

• Insightful Reflexes Requires Intelligence 13
• Combat Expertise Requires Intelligence 13

At first level (character creation), the number of skill points given is equal to (Class modifier2: Clerics, Favored Souls, Fighters, Paladins, Sorcerers and Wizards
4: Barbarians and Monks
6: Bards and Rangers
8: Rogues + Intelligence modifier) * 4. At each further level gained in a class, a character receives a number of skill points equal to Class modifier2: Clerics, Favored Souls, Fighters, Paladins, Sorcerers and Wizards
4: Barbarians and Monks
6: Bards and Rangers
8: Rogues + Intelligence modifier (with a minimum of 1 skill point).

Note: Even if your Player Character's race starts with 6 Intelligence (Half-Orc), and your Player Character's class gets 2 base skill points per level (Cleric, Favored Soul, Fighter, Paladin, Sorcerer, or Wizard), your Player Character will still get 1 skill point each level.

IMPORTANT: Both Feat Pre-reqs and Skill Points Only take into account three sources/bonuses when determining your Intelligence/Intelligence Modifier:

• Base ability value at Character Creation
• Level-Up ability point raises
• Inherent Bonuses from Ability tomes

Raising Intelligence Scores

You can raise your Intelligence score from different sources, among them:

Base

• During character creation, you can add up to 10 points to your basic Intelligence score, which means:
  • A Deep Gnome, Gnome, Drow Elf, Morninglord character can start with a Intelligence of up to 20
  • A Half-Orc character can have a Intelligence of up to 16.
  • All other races can start with a Intelligence of up to 18
• At the 4th, 8th, 12th, 16th, 20th, 24th, and 28th, you are allowed to raise a single ability by 1 point.
• The ability point raises are often referred to as "level-ups". These increases count towards Feat Pre-requisites.

Inherent bonus

Inherent bonuses stack with all other bonuses and also count towards Feat Pre-requisites.

• A Manual of Clear Thought will raise the Intelligence score by the appropriate value. For more information, refer to Ability Tomes. These bonuses will show on your character sheet in the Feat section.

Theoretical maximum

The theoretical Sustainable maximum for Intelligence for a caster is 129 using a Sun Elf, Drow, Deep Gnome, Gnome, Eladrin, or Chaosmancer Wizard 20. Note that this is not necessarily ideal for builds, just that it can be done.

The Breakdown is as follows:

• 20 Base (Spend 10 build points to get max possible for Race), Eladrin has base 18, but gets a unique +2 from Winter Affinity
• +7 Level-up
• +8 Tome
• +2 Racial Enhancement (6 AP)
• +9 Class Enhancements
  • +10 from Pale Master (41 AP, Shroud of the Lich +2, Improved Shrouding +2, Tier 3&4 Intelligence +2, Capstone +4)
  • +4 from Harper (24 AP, Core 2, Core 4, Tier 3, Tier 4 Intelligence +1)
  • +1 from Archmage (12 AP, Tier 3 Intelligence +1)
• +2 Racial PL Feats for Drow and Gnome
• +2 Racial Completionist
• +2 Completionist Feat
• +5 Epic Feat (Great Ability x5)
• +16 Item Enhancement Bonus (Currently only obtainable on random-gen gear with both Wondrous and Masterful craftsmanship, making it exceptionally rare.)
• +7 Insightful(Item, Random loot (Legendary Greensteel +7 max)
• +2 Exceptional(Isle of Dread, Viktranium Experiment--yes, you can get this bonus on Legendary Greensteel, but since greensteel and alchemical crafting items cannot have sentience on them, this bonus then becomes exclusive with the alchemical bonus)
• +3 Quality
• +2 Festive Event Augment
• +4 Artifact (Solar Gem of Intelligence)
• +2 Guild Airship Buffs
• +19 Sentient Filigrees (+12 in 10 weapon slot, +7 in 5 minor artifact slot)
• +4 Profane(Lunar Gem of Intelligence)
• +2 Alchemical (Alchemical crafting weapon))
• +2 Competence (Bard Inspire Excellence song)
• +2 Yugoloth
• +2 DDO Store Potion
• +2 Primal Avatar Spirit Boon: Mind
• +2 Fatesinger Glitter of Fame + Arcane Resonance
• +2 Fortune (Curse of Major Intelligence)

The theoretical Sustainable maximum for Intelligence for a non-Caster Character is 130 (Situational/Sustainable) using a Sun Elf, Drow, Deep Gnome, Gnome, Eladrin, Chaosmancer, or Dark Bargainer Fighter 12/Rogue(or Artificer) 8.

The only difference will be the Class & Patron Enhancements.

• +10 Class Enhancements
  • +8 from Kensai (21 AP, Power Surge +8 Intelligence)
  • +2 from Mechanic (Or Battle Engineer (22 AP, Tier 3 & 4 Intelligence +2)
  • +4 from Patron Enhancement Harper Agent (22 AP, Core Intelligence +2, Tier 3& 4 Intelligence +2)

This yields a +1 Intelligence difference from the Wizard 20 version above.
