Damage bonus

[Metux]

I have some basics questions about adding damage bonuses:

When you have a trait like +1 damage to undead with this trait for example:

Subject of study (carrion crown)
Years of study have improved your combat effectiveness against your chosen foe. Choose a non-humanoid creature type (and subtype if outsider). You gain a +1 bonus on damage rolls against creatures of this type. See the ranger favored enemy suggestions for a list of creature types most likely to appear in this campaign.

Lets say we use a dagger 1D4 19-20/x2 with 10 strengh and a positive channel of 1D6.

1) When you do a weapon attack, you do 1D4+1 and if you crit you add 1D4+1 (because they dont say it doesnt)? or its (1D4) +1 and when you crit (1D4+1D4)+1 ?

2) If you channel to harm undead, do you do 1D6+1? (then halve the result if they resist).

3) When you do a weapon attack combined with a channel smite, what do you do? 1D4+1 +1D6+1 ? or (1D4+1D6)+1 or 1D4+1 +1D6?

4)What happens if you use a shocking grasp for example? and with spell strike?

Thanks !

1) Generally, all constant damage modifiers are also multiplied on a crit. There are exceptions. For example, precision damage is not multiplied on a crit. In this case, you're looking at 2d4+2 damage if you crit.

2) Modifiers to damage rolls generally only apply to weapons (and weapon like spells) unless it states otherwise. So no bonus to the channel damage.

3) For Channel Smite, first work out the damage from the attack (normal or crit) and then add on the extra damage from the Channel Smite. The Channel Smite damage is not multiplied on a crit.

4) Spellstrike has special rules for interacting with critical hits:

Quote:

This attack uses the weapon’s critical range (20, 19–20, or 18–20 and modified by the keen weapon property or similar effects), but the spell effect only deals ×2 damage on a successful critical hit, while the weapon damage uses its own critical modifier.

But lets say you have shocking grasp at 1D6 damage. Does it deal +1 damage? (not talking about critical strikes there).

Because if it was ray of frost you would get +1 damage right? It's a weapon like spell.

If you could spell strike with ranged ray of frost and a bow, you do get +1 damage from the weapon and for the spell right?

[wraithstrike]

You would get the +1 from the trait for all of these.

In general, you can receive a weapon damage modifier on any spell that requires an attack roll and deals hp damage.

If you Spellstrike with a spell that can normally receive a damage modifier... I believe you still only get the damage modifier once, since it's still only a single attack. I'm not certain on this, however, so if someone else can confirm, I'd appreciate it.

For the nature of the damage bonus, it says:

You gain a +1 bonus on damage rolls against creatures of this type

When I read it, I would believe that anything that deals damage on such creatures get 1 additional damage.

Ray of frost deals 1D3 so it becomes 1D3+1. (Attack to hit or nothing)
Channel deals 1D6 so it becomes 1D6+1. (Will DC to halve)

For the channel example if we look at sun domains first power:

Sun's Blessing (Su): Whenever you channel positive energy to harm undead creatures, add your cleric level to the damage dealt. Undead do not add their channel resistance to their saves when you channel positive energy.

If we are level 1 cleric, and compare both bonuses:
- add +1 to the damage dealt (sun domain)
- gain +1 on damage rolls (from the trait, and its untyped by this way)

[wraithstrike]

That is right.

Thanks a lot :)
