Guild Wars 2

Does it scale up with any of the attributes, apart from hunger increasing life-force pool?
Does armor/weapon have any effect on DS?

As far I know, Vitality increases the overall life force pool.

Pretty much this, i believe it was worked out on a thread not so long ago that your Death Shroud HP is equal to your 120% of your max health and then +0% to 30% of that figure depending on how many points you have in Soul Reaping.

So me for example with base 916 Vitality (18,372 HP) and 15 Soul Reaping points will have 25,353 (22,046 + 3,307)

So weapons, armour and/ or runes that boost vitality will affect how much health you have in Death Shroud, just remember it wont decrease the amount it naturally depletes (4% of max per second/ 3% with trait), just the incoming damage from players or mobs.

Toughness helps in DS, but doesn’t get improved. I think you can also swap weapons while in DS for the sigil, and I’ve heard other people say to swap to staff in DS as you’ll do more damage – if this is true then weapon stats do contribute to DS damage
