10 Double Stab

Explanation: 10 double stab is needed for triple stab, and none of the other 1st job skills are immediately useful. The rest of your SP is best saved for the next job advancement.

20 Booster
2 Disorder

Explanation: Although dumping into triple stab directly would give more average damage than going mastery first, you’re mainly concerned with stability during these levels trying to consistently kill a monster in x amount of hits, so overkilling won’t be of much help. 6 triple stab to start off for the third target, then mastery for the consistency. If you need dark sight for party quests and such, take a few points from booster for it.

Explanation: Triple stab will still be your best mob skill until level 70, so focus first on self haste to improve your mobility. Slash storm is a decent mob skill with farther range than triple stab along with being the first skill that moves you, so get that next to integrate it into your training for even better mobility and mob damage. Fatal blow then comes next after your training skills as a strong single-target skill. After that, get nimble body for the extra accuracy and avoid.

Explanation: Tornado spin and flash bang are not very good skills, so max flash jump for mobility and save the rest of your SP for the next job advancement. Tornado spin gives you a nice rushing skill, but you get flying assaulter anyways in a few levels. 1 point is good enough for a 55-69 rushing skill to create triple stab mobs. Flash bang is really only useful for blinding bosses and luring typhons, both of which are not very relevant until later on anyways. If you think you’ll be training on typhons later on, you’ll be needing flash bang anyways, but if not, just leave it out until the end of third job plus.

Explanation: This build is specifically for starting off at typhons right away at level 70. Upper stab is extremely fast, so with maxed upper stab, you’ll be doing tons of damage spamming upper stab at the safe spot just as an archer does with arrow rain/eruption. Flying assaulter starts off low because at level 70, you’ll probably be killing slow enough that typhons will be flying into your mob faster than you can kill them, so there’s not much need to lure. Slash/bloody storm is really only used for movement and invincibility at typhons, and 1 point upgrades your slash storm to bloody storm. As you kill typhons faster, flying assaulter becomes more important to add typhons to the mob, so get it to hit 8 targets next. Mirror image increases your upper stab damage by a ton as well as adding damage to your other skills, so that comes next. After that, get 11 flash bang for the added range and targets, as it’ll be very useful to throw to the opposite side of the map once per lure cycle. Bloody storm and tornado spin expand your training options with galloperas, himes, newties, etc., then add the rest of your needed skills is whichever order you want. Make sure you get maxed flash bang for later bosses and maxed dark sight for chains of hell.

Explanation: Venom, final cut, and sudden raid are all great first-pointers. Since you’re using so many skills to train in early 4th job, it’s best to start with venom and thorns because they affect all the attacks you have. Thorns gets the last of its irregular boosts at 12, so get a decent venom when thorns is at 12. Venom is really good for dual bladers because the extremely fast mobbing attacks trigger venom much more often than other thieves’ skills do, not to mention even sudden raid activates it. I choose to leave sudden raid at a low level because you’ll be training off royal guard and other bosses soon enough, and keeping it at a low mp cost keeps it great as something to activate venom on monsters in other parts of the map. I also don’t think it does enough damage to be worth purely spamming anyways, and dual blader damage is much less stable than magicians’ especially with criticals and the random venom effect. After thorns is done, chains of hell comes next for better single-target damage. A good thing about the dual blader 4th job is that all your training attacks are already maxed back in 3rd job plus. Once chains of hell is finished, stack effect comes next for royal guard as well as other bosses like anego, etc. Although stack effect is almost completely useless outside of royal guard and similar bosses, killing royals is the fastest exp rate achievable in the game and is definitely worth being the sole reason for getting 26 stack effect. Because you won’t be able to hit royals efficiently enough until like level 155, I set it up so that stack effect would hit 26 at that level. Final cut comes next to improve your soloing damage, and maple warrior next to further improve your damage, then you’re pretty much done with useful skills in your 170s like almost all other classes.
