Thorns Aura vs Negative Vampiric Aura

[sethmachine]

Hi,

What are some of the differences between a standard Thorns Aura and a Vampiric aura with negative life gain?

 

[Solu9]

You receive damage from damaging a unit with Thorns Aura.
You receive damage from damaging anything (that is allowed) with a neg Vampiric Aura.

Right what would this mean in terms of gameplay for a negative vampiric aura that only targets enemy units?

 

[Solu9]

The same.
Let's say you want to avoid receiving damage.
Thorns: You just skip these enemies and kill everything else.
Neg Vampiric: You skip everything.

Edit:
What I meant by "allowed" was that if the Neg Vampiric only works for organic units I would still attack mechanical enemies.

A negative vampiric aura that affects enemies would make the enemies effected take damage whenever they attacked anything as long as they were in range of your aura. Even if the unit they are attacking isn't in range of your aura.

Thorns aura would make enemies take damage whenever they attacked a unit in range of the aura. It wouldn't matter if the enemies were out of range, they would still take damage from the aura as long as the ally they attack IS in range.

Practically speaking, there's not too much difference there. The biggest difference would honestly be what Solu said: Units under the effect of the a negative vampiric aura wouldn't take damage when they attacked mechanical units.

I am guessing negative vampiric aura will result in nonsense kills (suicides) since it may not actually deal credible damage. Thorns aura should deal damage back from the damaged unit to the source correctly crediting them as the killer.

There is also the logical side to it. Thorns aura is defensive meaning the damaged unit uses it. Negative vampiric aura is offensive meaning that the damage source (damager unit) uses it.

There is also likely a problem related to how damage is dealt. Life steal only absorbs damage taken so negative will deal damage based on the damage taken by the target. Thorns reflects the damage dealt to the target (before reductions) so can reflect more damage than taken (especially in the case of high amounts of armor). Not entirely sure, but I remember observing this over time.

Oh I didn't even think of the Vampiric aura's negative effect was to damage the attacker, but it seems obvious to me now.
I was going from the approach that the unit with the aura negatively healed when dealing damage.

Another difference between the two is that the negative vampiric aura will be cancelled by positive vampiric aura while thorns aura would counter negative thorns aura and not be canceled by vampiric aura so an positive thorns aura is more beneficial than an negative vampiric aura.

The main concern is kill credit. Since vampiric aura is designed to heal I doubt it will register as taking damage from any source so it will appear the unit was killed by null and not award experience or bounty.
