Okay,

Lets put this topic where its supposed to be:

How does Horde Damage work?

Melee:

1 per hit + 1 per two DoS

Additional +1 if you are using a power weapon

Ranged:

1 per hit, +1 if you are using an Explosive (X) Weapon

1 magnitude damage per Blast (X) rating

But how do we apply certain talents and special abilities:

**Unrelenting Devastation:**

Double Damage per hit or when using Blast (X) weapons just add 1d5 after all other hits have been resolved

**Storm of Iron:**

Doubles Magnitude Damage (When do we apply this?)

**Metal Storm Bolt Shells:
**Bolt Gun gains the blast (2) special quality

So how do these 3 powers work in concert?

**The Question:**Morgan, a Storm Warden Devastator Marine fires his Heavy Bolter at a horde of Tau Fire Warriors, he scores a tremedous 10 hits, to make sure he cuts the horde down to size he uses Metal Storm Bolt Shells

2d10+8, Pen 4, Tearing Blast (2)

**My solution:**Since he is using a (X) based weapon he receive a bonus hit so he hits 11 times (we assume he wounds).

He is using a weapon with Blast (2) so that is 2 damage per hit makes 22 Magnitude damage

Now all hits have been resolved and we add +1d5 magnitude damage for Unrelenting Devastation (we rolled a 9, so +5)

Now Morgan causes 27 Magnitude Damage....but we are not finished yet...

Morgan is a ery experienced Storm Warden and has recently bought the Storm of Iron Talent which doubles Magnitude Damage

27 x 2 = 54 Magnitude Damage in Total...
