Mechanics of Traps

Hello

I was wondering if someone could explain how trap mechanics work.

For example from http://www.pathofexile.com/forum/view-thread/11707

Traps
Traps are very similar to spells, but are not affected by cast speed or spell damage mods. They are affected by % trap laying speed, and relevant damage mods. Integer damage bonuses on gear are not added to trap damage.

This seems to hold true with +spell damage passives, but if I equip a wand with +10% spell damage on it, it increases the damage of my fire trap.

Does this mean that the fire damage portion is considered a spell (so a bear trap will not be modified by this), or does it mean that only passives with +spell damage don't work with traps and weapon mods do ?

Does the above hold true for things like + elemental damage as well, as I saw no change to my trap damages when taking the + elemental damage passives.

Why does my Wrath aura increase the damage of my bear traps then ?

Can traps crit, and is this modified by global crit chance ?

Anything else I should know ?

Sorry if this had been discussed in another thread but I did a search and couldn't find any coherent answers.

Thanks in advance.

I was also searching for an explanation of traps mechanics, as most of them seem pretty obscure.

Can anyone tell us whether:

-traps are or not affected by cast speed? the "cast speed" in my char sheet is modified, but official sources say it should not. I suppose that's what "trap laying speed" should do?

-traps' trigger radii are all equal, or do they differ between the various traps/the support gem? And will increased AoE/concentrated effect change it?

-how is the lock duration of Bear Trap calculated?

-there's any way, through passives or uniques, to make traps recharge faster/store more than 3 at a time?

Thanks in advance:)

I'm currently a level 59 fire trap marauder and it is amazing - I definitely recommend it if you're thinking about making a trap build.

Anyway, I believe fire trap is a spell (as it says it is in the tool tip), however, it isn't affected by spell damage nodes. It IS affected by elemental damage nodes and fire damage nodes. Fire trap is also affected by increased burn damage nodes and increased burn duration nodes. BUT: increased burn damage only affects the burning GROUND; not the IGNITE. This is because the ignite damage is a set number based on the damage the original fire damage dealt. Increased burn duration DOES affect ignite.

Fire trap is affected by increased area of effect nodes as well :)

When it says integer damage mods don't affect traps, it's talking about things like "Adds 3-30 lightning damage" on a ring. Relevant % mods should still apply, including elemental damage passives (but not WEAPON elemental damage passives) and spell damage. Bear trap is kind of an exception, dealing damage that's not considered weapon damage or spell damage, and is purely physical.

Bear trap's lock duration is based on damage, but i'm not sure of the exact formula.

Traps can crit.

Traps aren't affected by cast speed. Trap laying speed only.

Trigger radius is the same for all trap types, I think, and is only affected by 'trap and mine trigger radius' bonuses, not usual AOE bonuses (this will increase the area of effect of the actual spell used by the trap, if it's an AOE spell, but won't increase the trigger radius).

If you want to store more than 3 traps, carry more than one of the same type of trap gem.

I might be wrong about some of this stuff.

IT'S A TRAP!
