Help with trap damage...Maybe just damage in general

[johnbragg]

Hey, me and a few friends are running a game of D&D for the first time, (we've gone with 3.5). None of us have ever played before and we're kind jumping in at the deep end.
I have a question about trap damage, say for instance you take the basic arrow trap:

CR 1; mechanical; proximity trigger; manual reset; Atk +10 ranged (1d6/×3, arrow); Search DC 20; Disable Device DC 20.

What exactly is the damage for this trap? Is it: 10 (melee damage) + (result of 1d6 roll, lets say "5") times the roll by 3 so the damage would hit for 25?
Also does it bypass your AC and hit straight for damage?

This has me confused for enemy damage too, some animals have +11 melee before their roll. Is this added onto the overall score of the roll?

Sorry if i'm being stupid, we have no reference to go off and have spent months learning as many rules as we can before we actually got together and played. Just a few things like this would be great to have clarified.

OK, I see the issue here. This is how you read the entry.

Atk +10 ranged (1d6/×3, arrow)

Atk The trap makes an attack roll against a character.

+10 Roll d20 for the attack roll and add 10. It hits an Armor Class equal to or less than that number.

ranged means that it's a ranged attack, if you have abilities or conditions or immunities or whatever that apply to ranged attacks they come into play here. (There are all kinds of special cases in 3.5, so they try to cover common ones.)

1d6 Roll 1d6 for damage

/×3 Unless you roll a natural 20, in which case you may have a critical hit. Roll another attack to confirm, and if it hits, multiply the damage by 3.

Attack rolls (used to be called "to hit" rolls in earlier editions, sometimes I still do) and damage rolls are handled separately.
