Indigo Tricksters combine skill, arcane magic, and deadly fighting technique to catch their opponents off-balance and capitalize their foes' lapse in defense to deliver a deadly flurry of blows. Indigo Tricksters love the challenges that adventure brings, and they relish finding unique and inventive ways to use their abilities. Their cunning use of illusion magic sets their opponents up, only to knock them down with a devastating onslaught of steel and arcane might.

If you like the idea of playing a dual-wielding roguish fighter with a synergistic arsenal of sneaky illusion magic, then the Indigo Trickster is for you. 

Indigo Tricksters have the following game statistics.
Abilities: High Dexterity is most important for an indigo trickster, as the AC, Initiative, and Reflex boosts all greatly synergize with class abilities. A high Strength is also important for indigo tricksters that rely on the stat to hit and deal damage. A good Intelligence makes your invocations harder to resist and also improves your AC. As usual, good Constitution greatly helps an otherwise squishy melee class.
Alignment: Any
Hit Die: d8
Starting Age: As rogue.
Starting Gold: As rogue.

All of the following are class features of the Indigo Trickster:

Weapon and Armor Proficiencies: As an indigo trickster, you are proficient with simple weapons, martial melee weapons (including those that can be used as thrown weapons), and light armor, but not with shields.

Invocations: You do not prepare or cast spells as other wielders of arcane magic do. Instead, you possess a repertoire of arcane-based attacks, defenses, and abilities known as invocations. You can use any invocation that you know at will. Invocations are spell-like abilities; using an invocation is therefore a standard action that provokes attacks of opportunity (unless the invocation lists a different cast time). An invocation can be disrupted, just as a spell can be ruined during casting. An Indigo Trickster is entitled to a Concentration check to successfully use an invocation if he is hit by an attack while casting, just as a spellcaster would be. You can choose to use an invocation defensively, by making a successful Concentration check, to avoid provoking attacks of opportunity. Invocations are subject to spell resistance unless an invocation’s description specifically states otherwise.

The save DC for an invocation (if it allows a save) is 10 + half your class level + your Intelligence modifier. Your caster level with invocations is equal to your class level. Each invocation has a spell level equal to half your class level.

The four grades of invocations, in order of their relative power, are least, lesser, greater, and dark. You begin with knowledge of one invocation, which must be of the lowest grade (least). As you gain levels in this class, you learn new invocations, as summarized on the Table and described below. A list of available invocations, along with their complete descriptions, can be found below.

At any level when you learn a new tier of invocations, you can also replace an invocation you already know with another invocation of the same or a lower grade. At 6th level, you can replace a least invocation you know with a different least invocation. At 11th level, you can replace a least or lesser invocation you know with another invocation of the same or a lower grade. At 16th level, a you can replace a least, lesser, or greater invocation you know with another invocation of the same or a lower grade.

Arcane Surge: The faint blue glow surrounding your weapons begin to grow larger and brighter with each successful strike. As your weapons become engulfed with arcane energy, you suck in the power from them to fuel your devastating attack.

Some of the invocations have two versions: a regular form and a stronger "surge" version. The surge version of an invocation costs a number of surge points to use and adds an extra effect to the invocation. Invocations with a surge cost of X require that you spend a minimum of 1 surge point to activate. In addition, all invocations can be cast without provoking an attack of opportunity by spending 1 surge point.

You acquire a surge point with each successful attack that you make against a creature with a melee or thrown weapon in combat, which you can then use to fuel your surge invocations. These points are stored until you either expend them or until the end of the encounter, whichever comes first. The maximum number of surge points that you can store at a time is one per class level.

Example: Ezreal is a level 6 indigo trickster and is fighting an orc. He is currently storing 4 surge points. He makes makes a full attack with two daggers against an orc. Three attacks hit, earning him 3 surge points, but he can only store up to 6 points at a time, so he only gains 2 to bring him to 6.

Quick To Act (Ex): You gain a +1 bonus on initiative checks. This bonus increases by 1 at 5th, 10th, and 15th level.

AC Bonus: Starting at 2nd level, you can add your Intelligence modifier as a bonus to Armor Class, so long as you wear light armor, are unencumbered, and do not use a shield. This bonus to AC applies even against touch attacks or when you are flat-footed. However, you lose this bonus when you are immobilized or helpless.

Two-Weapon Fighting (Ex): The path of the Indigo Trickster teaches how to effectively wield two weapons at once. At 3rd level, you gain Two-Weapon Fighting as a bonus feat even if you do not qualify for the feat. If you already have Two-Weapon Fighting, you may take a combat feat as a bonus feat, so long as you meet all the prerequisites for that feat.

At 6th level, you gain Improved Two-Weapon Fighting as a bonus feat even if you do not qualify for the feat.

At 11th level, you gain Greater Two-Weapon Fighting as a bonus feat even if you do not qualify for the feat.

At 17th level, you gain Perfect Two-Weapon Fighting as a bonus feat even if you do not qualify for the feat.

The benefits of these bonus feats apply only when you wear light or no armor. You lose all benefits of these bonus feats when wearing medium or heavy armor.

Lowered Guard (Ex): Cracks in your enemies' defences appear when you surprise them, which you and your allies can further exploit. Starting at level 4, when you actively deny an opponent of its Dexterity bonus or strike an opponent currently denied its Dexterity bonus, it takes a -1 penalty to its AC until the beginning of your next turn. This penalty takes effect before resolving your attack and is not cumulative. This penalty increases by 1 at level 8, 12, 16, and 20.

Arcane Fission (Su): Your battle-focused arcane abilities allow you to wield your favored weapon in both hands by splitting it into two identical weapons. At level 5, if you're holding a melee or ranged weapon you are competent with in one hand and nothing in an empty hand, you may create a duplicate of the weapon that forms in your empty hand. This duplicate is made of pure arcane energy but otherwise acts identically like the original weapon, including any enchantments and effects the original weapon has except for any limited use abilities or material properties. The weapon is treated as a light weapon when wielded in your off hand. The duplicate weapon dissolves into nothing if it's not in your hand by the end of your round, or immediately if anyone else holds it. Creating a duplicate weapon is a free action.

Trickster's Savvy (Ex): Starting a 7th level, your Indigo Trickster level is equivalent to a rogue's for determining whether or not you can flank a creature with the Improved Uncanny Dodge ability. If you have Rogue levels, they stack for the purpose of this ability.

Evasion (Ex): At 7th level, you can avoid even magical and unusual attacks with great agility. If you make a successful Reflex saving throw against an attack that normally deals damage on a successful save, you instead take no damage. Evasion can be used only if you are wearing light armor or no armor. If you are helpless, you do not gain the benefit of evasion.

Uncanny Agility (Ex): Beginning at 9th level, you may spend 2 surge points to take an additional swift or immediate action. This additional immediate action does not count against your swift actions on your next turn. You may only use this ability once per round.

Impenetrable Illusions (Su): At 13th level, you've developed such skill with the arcane arts that it's nearly impossible to detect your invocations with divination magic. When anyone employs a divination spell, spell-like ability, or magic item (such as detect magic) that may detect the magical aura of one of your invocations, the wielder must make a character level check (DC 11 + your class level) to successfully detect your invocations. Similarly, anyone attempting to use a divination such as see invisibility to reveal the effects of one of your invocations must make a level check to reveal your spell's effects. The divination user can only check once for each diviniation spell used, no matter how many of your invocations are operating in an area.

Improved Evasion (Ex): From 14th level on, you gain the benefit of improved evasion. You still take no damage if you make a successful Reflex save against an attack, and even if you fail the Reflex save, you take only half damage from the attack. If you are helpless, you do not gain the benefit of improved evasion.

Unseen Steps (Ex): As you near the end of your path, your arcane magics become so seamlessly tied to your fighting style that the mundane has become magic. Starting at 18th level, for every two successful attacks that you make in a round, you may teleport yourself 5 feet in any direction as by greater teleport at the end of the attack. 

Arcane Alarcity (Su): Beginning at 19th level, you learn that energy and speed are one in the same, and apply that knowledge to your invocations. By spending an amount of surge points based on the invocation's grade, you may change the invocation's casting time to a free action. Least cost 4, Lesser 8, Greater 12, and Dark 16.

Limit Break (Ex): At 20th level, you can supercharge your nerves with arcane power, allowing you to react at unthinkable speed. You may activate this ability to take additional swift or immediate actions this round. The first additional swift or immediate action costs 2 surge points, with a cumulative cost of 1 surge point per further use of this ability (3 surge points for the second swift immediate action, 4 for the third, etc.). This additional immediate action does not count against your swift actions on your next turn. You may only use this ability once per encounter.

Multiclass Characters and Prestige Classes:
You may benefit from prestige classes in the same manner as warlocks. Taking levels in a prestige class that have have “+1 level of existing arcane spellcasting class” or “+1 level of existing spellcasting class” grants new invocations known and an increased caster level when using your invocations as though you had gained a level in the indigo trickster class. You do not, however, gain any other indigo trickster class abilities.
You cannot qualify for prestige classes with spellcasting level requirements, as you never actually learns to cast spells. However, prestige classes with caster level requirements are well suited to you. Your caster level for your invocations fulfills this requirement.
Even when you gain levels in a different class, the amount of Arcane Surge points that you can hold grows larger. Determine the maximum number of Arcane Surge points that you can hold at a time by adding your indigo trickster levels + 1/2 your levels in all other classes.
