“BRK, I have a question about Lightning Breath. I saw your post about Gore vs Claw, so how about we make this a 3-way-match and rank them one through three…Which is most efficient and will cause the most damage. Thanks, Drizztz.”
Nope, we’re not gonna do it.
Why? Because of Spell Damage. Yes, it’s Math Time at BRK High.
Although we though so originally, neither Claw nor Gore gain any bonuses from a pet’s +Spell Damage, which is derived from the hunter’s RAP. We cannot find a Blue Post or a definitive “yes/no” answer anywhere confirming this, but from carefully monitoring our cat’s Claw, we have no choice but to report what our own eyes tell us.
However, it is a very-well documented fact the Lightning Breath most certainly does scale with +Spell Damage. In fact, it was heavily nerfed a few patches back. It’s an interesting subject, the LB Nerf. So interesting, in fact, that we should revisit it.
The formula for Lightning Breath is:
LB Damage = Base Damage + Spell Power Damage
Your pet’s Spell Power Damage was calculated by using a factor of your hunter’s RAP, and that looked like:
Spell Power Damage = RAP * 0.125
So our formula looked like:
LB Damage = Base Damage + ( RAP * 0.125 )
If you were a Marksman with 2300 RAP, your windserpent’s LB damage would be:
LB Damage = [ ( 99 + 113 ) / 2 ] + ( 2300 * 0.125 )
LB Damage = 394
And can you see why Marksmen hunters went nuts for Lightning Breath? It was obscene.
The problem was that the wrong formula for calculating the Spell Power was used. Lightning Breath is an instant-cast spell. Spells that are instant-casts are only supposed to receive a percentage of +Spell Damage, the specific number being 42.86%. Supposedly, everybody’s instant-cast spells use this modifier but the hunter-pet programmers didn’t know it. Thus, the LB Nerf was actually correcting a mistake in the formula. In its current form, the LB damage formula now looks like this:
LB Damage = Base Damage + ( RAP * 0.125 * 0.4286 )
Using our previous data, we get:
LB Damage = [ ( 93 + 113 ) / 2 + ( 2300 * 0.125 * 0.4286 )
LB Damage = 226
If you were wondering why the Marksman Hunter Community was outraged at the “Nerf”, now you know.
So why won’t we do a comparison of Lightning Breath, Claw and Gore? Because, as you can see, for each hunter the comparison will be different. As a BM hunter, BRK’s RAP is approximately 1700. If we had a serpent with Lightning Breath, his LB damage would be 194, which is 30 damage less than a Marksman hunter with a 2300 RAP. Also, Claw/Gore can be mitigated by armor whereas Lightning Breath is Nature damage. To do a true comparison, we’d have to take different damage-mitigation factors into consideration and, frankly, we’re not that motivated.
We recommend people not spec survival unless you have a very high agility to take advantage of Expose Weakness. Similarly, we don’t recommend Lightning Breath pets to hunters unless they have a RAP high enough to really pound out the nature damage as opposed to a melee pet that does naturally-high Claw/Gore damage. But if you do have a massive RAP, a Lightning Breath pet is a fabulous choice for you.
