Dragon Nest

I've revamped this thread a bit...a bit of cosmetic changes and such. Archived version here.

With regards to how the suffix system works, try reading this thread. Armor and Weapon suffixes works independently. Try this thread for the differentiations.

Disclaimer:

• This is the time I'll like to bring out my point of view regarding some suffixes choices. Please feel free to give your contructive criticism/point of view. This is not a guide.
• For clarification purposes, I'm not an expert in any of the mechanics field of Dragon Nest. However, I'll try my best to answer questions. If anyone has a better explanation, feel free to shoot.
• The suggestions are specifically for the Sorceresses and Clerics(zooming in to Priests and if applicable, M.Atk skill orientated Paladins w/ Light spells.)

For other classes, you might want to into this thread, as different combinations yields different results.

Well, here I go.

Sorceresses

Recommended Weapon Suffixes: Double Intel Weapons

Why is the Magic Power and Int Weapon Suffix Combo not recommended now?

• The old Magic Power and Int combo was for the old suffix system. The old suffix system is outdated.
• The Magic Power's slight increase in raw attack just isn't worth the trade of the usefulness of the Intel Suffix should it activate. Also, activation chance and effects stacks with the same weapon suffixes.

Why is the Double Int Weapons recommended?

• The debuff effect will be revamped ito a very powerful 10s -x% elemental resist debuff.(Giving a damage increase over 10 seconds) Chaose
• There is no suffix there's more powerful than this. Chaose
• Party members who has elemental skills will also deal more damage since it's actually a debuff on the target. Chaose
• Intel debuff from various weapons(Including party members) all stack. Chaose
• Debuff Effect takes the total amount of resist reduction instead of only one's weapon resist reduction.(Since weapon suffix effect stacks) Chaose

Here's how it stacks. 

Example: Member A activates his/her suffix effect on the adversary, which decreases the enemy's elemental defense by 10% (i.e. -10% elemental def.) 5 seconds later, Member B also activates his/her suffix effect on the opponent(Assuming that by default, if there's no stacking involved, it'll be a 10% decrease in elemental def.), which decreases the enemy's elemental def. by another 10%. Observe.

• 0-5 seconds: -10% elemental def. on enemy
• 5-10 seconds: -20% elemental def. on enemy
• 10-15 seconds: -10% elemental def. on enemy since the first activation expired.

From Chaose.

Why not Magic Power or the Elementals?

• Magic Power and the Elementals only give additional damage to one hit, while the Intel suffix gives a debuff in 10 seconds, and is stackable. (The Intel suffix would seem more superior, no? They share the same cooldown of 30s, by the way) Chaose

   Dark suffix and other elemental suffix when fixed as I know would work like Dest and Mag. Those suffix would only affect 1 hit of your attack. Which means that you would only boost 1 hit of your attack for every 30 secs.

Comparing Magic Power vs Intel raw stats via Manticore Weaponry-

 Main Weapon 

Magic Power:

• M.Atk: 299-405 
• Intel: 21
• Crit:1053
• Agi:14

Intel:

• M.Atk 284-385
• Intel: 42
• Crit: 861
• Agi:28

Note that the difference in M.Atk is around 15 to 20. Taking into consideration of Intel debuff and more Int, the difference is not that much in terms of raw damage, but Intel's debuff utility is way better. However, you'll be losing around 200 critical if using Intel. That'll be the only downside. Even so, Crit can come from other equipment and/or such. The Agi stats for Intel is higher than Magic Power too. To summarise:

• M. Atk difference: 15 to 20. Intel Suffix has more Int.
• Intel Debuff > Magic Power Debuff
• Intel Crit < Magic Power, MP around 200 Crit more.
• Intel Agi > Magic Power Agi

Sub-Weapon

Magic Power:

• M.Atk 174-263
• Intel: 18
• Crit: 73

Intel:

• M.Atk 142-214
• Intel: 30
• Crit: 73

For this case, Magic Power's M.Atk difference is higher, around 30 to 60 or so(Estimated). But, Intel difference is also quite significant. If needed, Agi's stats for Staff is higher than Agi's stats for Magic Power. This means that crit wise, Magic Power actually loses out here. Also,do take Intel's debuff into consideration. So,

• Magic Power's M.Atk > Intel's M.Atk around 30-60
• Intel Int > Magic Power Int
• Int Debuff > Magic Power Debuff
• Intel overall Crit > Magic Power Crit due to higher Agi

Recommended Armor Suffix Combinations: 

• HP and Intel Armor Suffix mix
• 4 HP 1 Int(Helm) 
• 4 HP 1 Mana(Helm) for the Elemental Lords due to usage of toggle shields. (Recommended by Saurus)

Why is Iron Wall not that useful now?

• The first hit that triggers it is not affected by the Iron Wall buff. Chaose
• The damage reduction only applies after the buff icon appears. Chaose
• A very long 2min 30s wait.

Why is HP suffix recommended in armor?

• Because Chaose says so  (Ok, just kidding. I really can't find a very detailed reason why, but mainstream Suffix combo is actually 4x HP and 1x Int(Helm) for FUs. That should be reason...enough? Anyway, Iron Wall is out, HP is life leech!)
• There are so many threads praising the usage of HP suffix. Seriously, just take a quick scan and you'll realise it's usefulness PvP wise. I'll give you an example. For PvE though, don't rely on it too much. Quoting from Koizell, "...the heal effect from the life suffix is not gonna help in SDN(you will kiss the floor before it takes effect)..."

To show you the power of Life Prefix and Mana Helm for ELs:

• Intel Main Weapon, Magic Power Sub Weapon
• Dual Intel

Previously, I've actually recommended Dual Intel because of the debuff. But recently, there was a discussion regarding Magic Power vs Intel in the cleric section, and someone pointed out this interesting fact:

TS what are u talking about? does that mean EL becomes overly overpowered again? or those which wield elemental attacks?

Since the elemental debuff is on the mob, that means those who wield elemental attacks gain damage boost(on the specific mob) if any of the Int user suffix activates. So far, it benefits EL, Priests, Paladins, FUs...I doubt the Archers/Warrior classes have elements.

Just don't use skills like those in the lazer line(For FUs) or physical attacks(For Paladins) which has no elements during the 10s...

Ah, this will be one of those questions which I could not answer. You'll have to ask a professional SM for that.
