I've been looking all over for a reliable source for DFO builds but cant seem to find one. I've been hearing the word Destroyer thrown around alot but cant figure out what skills make a Destroyer. Someone help!!!!

you purchase this from the fighter trainer.. basically buffs your defense and melee i believe at the cost of a Mana penalty and that you no longer are able to cast elemental magics or higher. which leaves you with witchcraft, spell chanting, GM and LM.

Destroyer is a skill you buy that increases your damage against someone holding a staff, and locks out all elemental schools of magic for you.

Most folks now are going Indestructable which increases your defenses by like 7.0. Since most folks can tell when you're in heavy armor that you're likely to be doing more damage when they have a stick out, they just put the stick away and run. Making Destroyer almost pointless.

That being said, if you're working on a new character Destroyer might be a good way to go, but once you get your masteries up on your weapons then you're gonna be hitting for cap anyway at which poing Indestructable makes more sense.

Either way you're locking out the elemental schools of magic so you'll only use one of these if you're not going to be a spell tosser. However, that doesn't mean you won't use any magic because you will still need Heal Self, Stamina to Health, and Witches Brew so that you can keep yourself alive. Additionaly you will want Mana to Stamina so that you can use all that mana, that you won't get much use of otherwise, to swing your sword and chase folks.

And to add, if your leveling up or working casting mobs, like beguilers and wilddtribe mages, get destroyer while your doing it. As long as they have their staff out, and they always do, you will enjoy the benefit.

I'm not a great at PvP, so take this criticism for what it is worth.

I think some people think that going Destroyer or Indestructible as an excuse to wear heavy armor. I would say Destroyer does not get any benefit because it only occurs when the target uses a staff. When you are in melee range, you are more than likely to see your opponent using a melee weapon, so there goes your benefit.

Indestructible gets some protections and 10 more HP, but unless you are super freaking awesome with a bow, you just lost your long range attacks. You do not have any AoE. And in my opinion, a weak AoE is better than no AoE. You can still wear all the plate you want, cast unburden and cast a few buffs on yourself from the elemental schools, and now you are better off than anyone with Indestructible. Plus you still have some debuffs or offensive ranged spells that the Indestructible doesn't have.

I say indestructible if you choose one of these specs, I am not awesome with a bow but wwhen buffed with archery haste even with my poor accuracy I could sustain equal dmg with a gravesong, if I had superior accuracy I would be way ahead honestly.

But imo if you want to be heavy armor just wear heavy armor and keep the added benefits of magic buffs

I think you could even make an indestructible using hybrid sets instead of heavy armor and using all the little offensive spells (blast, rend, needle etc.).
Not as efficient as a pure mage, more like "surprise, I'm not a noob and I don't care too much about your fireball".

Destroyer =

High damage bow
Infernal Armor
r60 or better 2hander + keen = nice
utility spells & heals
FTW

Pointless at this time, patch MAY change this but doubtful yet.
