In thisPathfinder KingmakerGuide we are going to take a look atOctavia. She is a Wizard that we are going to turn into anArcane Trickster, which is a very powerful Prestige Class. Octavia’s Arcane Trickster is a multiclass build that can seem complicated on first look, but is easy to use and naturally progress due to dealing massive damage.
Pathfinder Kingmaker Builds - Octavia
This build focuses on usingRay Spellstogether with theSneak attackbonus to do massive single target damage, with added AoE damage for good measure. Arcane Tricksters automatically receive the following Feats and abilities:
Octavia also has thePhysical Enhancementability where she can turn on bonuses to either DEX, CON or STR. Before you getCat’s GraceI would suggest using DEX enchantment and afterwards switching to CON. That way you get bonuses to 2 different Attributes.

Attributes
DexterityandIntelligenceare the most important attributes for an Arcane Trickster. A Dexterity modifier is added to every Ray Spell attack roll due to them falling into theRanged Touch Spellscategory. Since Intelligence increases the number of spells you can use per day, starting off adding 2 points to DEX and INT is recommended, so that you have the base modifier for both at +5. The last point you get at the game start can be put wherever you want.
There are some skills that are more important then others and you will have enough points to level most of them to high ranks thanks to high INT.Stealthis a good choice to start the battle without enemies spotting you, and it adds the Sneak Attack bonus to your first attack.Knowledge (Arcana)enables you to copy Spells from Scrolls to the Spellbook and can be used to identify magic items and monsters.Use Magic Devicelets you use Scrolls and Wands, making it a very good choice.

Due to the Ranged Legerdemain feat,Trickeryis fantastic in dealing with traps and trapped chests. Investing 4 points intoMobilityis a must because it is a requirement to unlock the Arcane Trickster Class.Perceptionlets you spot traps among other things, making it an ideal combo with your Trickery setup.
Classes&Feats
Octavia starts with 1 level inRogueand 1 level inWizard. The Arcane Trickster class can be unlocked when all requirements are met. Follow these tips to maximize build efficiency.
Besides Accomplished Sneak Attacker, these are the most important feats to get:

Damage Spells
There are many amazing spells to chose from but we will focus on Ray Spells. Ray Spells are Ranged Touch Spells that can strike an opponent once or multiple times. Octavia starts off with 3 Ray Spells:Acid Splash,Ray of FrostandJolt. These are great starting spells because they have infinite uses. However, the 3 most powerful spells for this build areScorching Ray,Hellfire RayandDisintegrate.
Hellfire Ray is just an upgraded Scorching Ray, and they both strike your opponent multiple times while adding your Sneak Attack bonus to damage for every ray. Disintegrate hits once but it hits very hard, usually killing an enemy instantly.

An important thing to know is that only Ray Spells can benefit from Sneak Attack until Arcane Trickster level 10 is reached, and the Surprise Spells feat is acquired. With Surprise Spells any spell can add your Sneak attack bonus to its damage. I have also added these damaging spells to the build but feel free to switch for anything you like.
Non Damaging Spells
Octavia comes withTransmutation SchoolSpecialization. That means you have 1 free slot in the spellbook every spell level (1 to 9) and you can select any option from the Transmutation School. However, there is a crucial spell that is not from the Transmutation School that you should look out for: it is calledSense Vitals. This spell allows you to perform Sneak Attacks automatically and it also stacks with other Sneak Attack bonuses.
As an example, if you attack a flanked opponent while Sense Vitals is active, you will deal normal Sneak Attack damage, just from flanking. Further Sneak Attack damage is added on top of that because of Sense Vitals.

There are many amazing buffing spells for this build and some of them apply to allies as well. Before reaching level 9, you can opt for spells like Mirrored Image, Cat’s Grace (Mass), Bear Endurance (Mass), Haste, Heroism (if there is no one else who can use this spell) and Reduce Person. These will help you out tremendously.
Upon reaching level 9 you get to use Fiery Body, an amazing buffing spell. After that you should get Heroic Invocation and Haste on top of Sense Vitals and you are ready to roll. Here is a list of all non-damaging spells you should take but feel free to add anything you like:
How toMetamagic
To “metamagic” any spell, open your Spellbook and click on the bottom right where it says Metamagic. From here you’re able to choose any spell and increase its levels byEmpoweringand/orMaximizing it.
Adding levels to spells means you need to slot them into a higher level slot. For example, Hellfire Ray is a level 6 spell and if Maximize is used, it will become a lvl 9 spell. It will then need to be slotted under lvl 9 spells in your spellbook.
Use Empower and Metamagic on Scorching Ray, Hellfire Ray and/or Disintegrate. Your spellbook should have 3 versions of Scorching Ray, Hellfire Ray, Disintegrate and anything else you want to have besides those 3. Do not forget that you may slot one spell multiple times. For example, you can have on your level 3 spells page Scorching Ray slotted 5 times if you want.
Arcane Trickster Octaviais a powerfulDPS buildthat can kill enemies instantly due to the stacking Sneak Attack bonuses and increased level of damaging spells amongst other things. Having someone in your party that can cast Heroism and Heroic Invocation is recommended, so that you save that lvl 9 slot for any of above mentioned spells.
Remember that Sense Vitals always stacks with the normal Sneak attack bonus, so make sure you are always doing normal Sneak Attack damage by focusing flanked enemies, using Impromptu Sneak Attack or attacking after going into stealth by using the spells Vanish, Great Invisibility and the Invisibility Thief ability.
Wizards have wide variety of spells to use so add whatever you feel like would be a good choice. Nothing here is set in stone besides Ray Spells.
