Arcane Pool (Su) You have a reservoir of mystical arcane energy that you draw upon to fuel your powers and enhance your weapon. This arcane pool has 4 points. The pool refreshes once per day when you prepare your spells. You can expend 1 point from your arcane pool as a swift action to grant any weapon you are holding a +1 enhancement bonus for 1 minute. These bonuses can be added to the weapon, stacking with existing weapon enhancement to a maximum of +5. Multiple uses of this ability do not stack with themselves.
Bonus Magus Arcane Pool Add +1/4 point to the magus' arcane pool.
Canny Defense (Ex) At 1st level, when a kensai is wielding his chosen weapon, he gains the canny defense ability. This is identical to the duelist prestige class ability of the same name (Core Rulebook 382), save that his chosen weapon may be of any type. [AC Bonus +1 / Actual AC Bonus +1]
Cantrips You can prepare a number of cantrips, or 0-level spells, each day. These spells are cast like any other spell, but they are not expended when cast and may be used again.
Diminished Spellcasting A kensai may cast one fewer spell of each level than normal. If this reduces the number to 0, he may cast spells of that level only if his Intelligence allows bonus spells of that level.
Dual Talent Some humans are uniquely skilled at maximizing their natural gifts. These humans pick two ability scores and gain a +2 racial bonus in each of those scores. This racial trait replaces the +2 bonus to any one ability score, the bonus feat, and the skilled traits.
Kensai Chosen Weapon (Whip) This is the Kensai's Chosen Weapon.
Kensai Weapon Proficiency (Whip) Kensai additional weapon proficiency selection.
Pragmatic Activator While some figure out how to use magical devices with stubborn resolve, your approach is more pragmatic. You may use your Intelligence modifier when making Use Magic Device checks instead of your Charisma modifier.
Spell Combat (Ex) You can cast spells and wield your weapons at the same time. This functions much like two-weapon fighting, but the offhand weapon is a spell that is being cast. To use this ability, you must have one hand free (even if the spell being cast does not have somatic components), while wielding a light or one-handed melee weapon in the other hand. As a full-round action, you can make all of your attacks with your melee weapon at a -2 penalty and can also cast any spell from the magus spell list with a casting time of 1 standard action (any attack roll made as part of this spell also takes this penalty). If you cast this spell defensively, you can decide to take an additional penalty on your attack rolls, up to your Intelligence bonus, and add the same amount as a circumstance bonus on your concentration check. If the check fails, the spell is wasted, but the attacks still take the penalty. You can choose to cast the spell first or make the weapon attacks first, but if you have more than one attack, you cannot cast the spell between weapon attacks.
Wayang Spellhunter: You grew up on one of the wayang-populated islands of Minata, and your use of magic while hunting has been a boon to you. Select a spell of 3rd level or below. When you use this spell with a metamagic feat, it uses up a spell slot one level lower than it normally would.
Weapon and Armor Proficiency A kensai is proficient in simple weapons and in a single martial or exotic melee weapon of his choice. A kensai is not proficient with armor or shields and suffers normal arcane spell failure chance when casting magus spells while armored.
