Shaman/Necro stacking
 

My wife made a necro recently and I made a Shaman. Someone told me their dot spells will not stack together (poisons and diseases). But if you can stack all dots you have of the same line, shouldn't the two be compatible?

its really not that big of a deal even if they dont stack, the necro will be using heat blood line of spells, along with the clinging darkness line, and allure of death (hp dot). So even if the disease/poison dot's don't stack you can easily work around it, and you can test if the poison/disease dots stack really easily, just go try it.

Think of a shaman as having two really powerful dots (except in the early levels), and a Necro having a ton of powerful to really powerful dots. Some of them overlap, but the necro has so many other dots it's not really a problem - most of what you're hunting shouldn't require all of a shaman/necro's combined ammo anyhow, and for tougher or named mobs, you can both go to town.

Plus, having the regen and other utility buffs (haste for the pet) makes Shaman/Necro a fabulous combination.

I'm fairly certain that even the exact same dot will stack, so long as it isn't cast by the same person. I remember this from earlier levels when a friend and I would both cast 'sicken' and I believe the mob's HP would drop 2x as fast if we both stuck the spell.

Don't think so. Pretty sure debuffs follow the same rules as Buffs, i.e. a stronger sow overwrites a weaker sow or a weaker sow fails to overwrite a stronger sow.

You may be thinking of WoW, where what you said is the case.

As a level 30 Necro, I'm currently using only 3 dots when fighting mobs: Engulfing Darkness, Vampiric Embrace and Heat Blood. Disease/Poison dots are ok, but these three accomplish more of what I need to do atm.

Engulfing Darkness, DoT + Snare
Vampiric Embrace, DoT + HoT
Heat Blood, DoT - my most powerful one at this level

My current highest level disease DoT is a PBAoE, which I don't really use and it's not that powerful atm. I do have another Poison DoT but again, it's not as powerful as Heat Blood is atm.

I could throw all 5 DoTs on the mob I'm fighting but that's pretty much a waste of mana. 3 DoTs + my buffed skeleton pet is all I really need just to solo. If you're duoing, I'd say only 2 DoTs are really needed, probably the Darkness line and Blood line, then throw in the Vamp HoT line when you need some health.

Necros need 2 spells to solo: Darkness and Disease cloud.

Turn off taunt, buff pet, pull with darkness, DC, and kite the thing until the pet kills it. Throw in the occasional tap and you are set. No down time.

Disease cloud.. the level 1 spell? they do this until 50?

Yeah, same spell Sks use for "perma" aggro. Pet does good dps from behind, plus snare dot damage. I would say they definitley could do it until 50, as its the most mana efficient way to level, not to mention super easy.
