INT Swordsman Recommended Build

Condensed recommended skill build for INT swordsmen:

Divine Shield - Master (Boosts DEF by 10%)
Ronin Slash - NA
Shogun Swing - Level 4
Cyclone Slash - Master (Long range attack.)
Tranquility - Master (Total defense of party boosted by 10%. Essential INT swordie skill.)
Arcane Punch - Master (But master it after all other important skills are mastered. If you don't have enough skill points, keep it at Level 2.)
Kamikazee - Level 2
Metal Body - Master (Total DEF boosted by 18%, plus caster is immune from all elemental effects.)
Lightning Strike - Master (Trademark INT swordie skill. Excellent for luring.)
Crescent Slash - Master (Long range attack. Essential for PK and CW.)
Sword Rings - Master (Long range attack. Slightly more powerful than Vacuum Slash, but less damaging than Tornado Slash. Unlike the Tornado Slash, it never misses.)

From the ETC tab:

Blade Mastery - Master
Lightspeed - Master (Mastered at character level 133.)

From the DEX tab (optional):

Sword Stab - Level 2
Multi Slash - Level 1

The DEX skills are intended to give INT swordies some versatility by adding some melee attacks to the mostly magical attacks (with slow casting times) located on the INT tab. It also helps somewhat in duels as the DEX skills above have canceling effects and are quick to use. It is not advisable to add points to your DEX just to get these skills. Use rings or enhanced suits to boost your DEX enough to learn them.
