Corrosive grenade mechanics tests

peddroelm · May 10, 2019, 7:45am

corrosive grenade test vs flesh * 0.6
lvl 38 Longbow corrosive cloud
Damage on card 6471 (per second applied 3 times per second) Active 8 seconds - 24 direct impacts ticks.
DOT on card 2205 per second

(tesla seems slightly better a raising bloodlust stacks since it hits 5 times per second EDIT wrong - there is a limit to the speed of stack growth … DOT grenades are vastly above it …)

6471 / (1292.766 / 0.6) = 3.00

72841.027 / 0.6 = 121401.71 was the total DOT damage at *1 multiplier
6471 * 8 = 51768 was the impact damage at * 1 multiplier

for this type of DOT grenade the DOT ticks greatly outweigh the damage inflicted by the impact ticks. +Elemental damage sources will have more impact on this type of grenade (when used against targets vulnerable to corrosion)

I noticed the enormous damage that corrosive clouds can do yesterday. I have rarely used these types of grenades, being misled by the card stats for years.

Your test shows 167 ticks of corrosive DoTs plus 25 direct impacts from a single deployment. That’s nuts! In comparison, an incendiary singularity grenade only causes 15 ticks of burn damage (if it procs) after a weak implosion effect (10%) and the initial blast.

The card stats suggest that the corrosive cloud grenade would do a single acidic blast followed by no more than 24 ticks of DoT damage. But in practice the grenade can deal 10 times more damage than we expect if the target remains in the cloud instead of fleeing.

I suspect that these cloud grenades deploy six overlapping sub-clouds. Each can inflict a DoT until the victim’s concurrent DoT stack is saturated (5?).

And the duration of the grenade’s effect exceeds 8 seconds by nearly 6 seconds! This could be a resolution of the stacking mechanism.

every time the mutihit grenades hit a target (corrosive cloud, tesla, fire) they roll to apply their DOT. The corrosive DOT last longer than fire/electric (8 seconds) .

The above test was done before the latest version of the combat logger so it doesn’t show the rolls to apply DOT …

Interesting. So the grenade’s cloud impact damage has 24 independent opportunities to trigger a corrosive DoT if the target remains in the green cloud? If the attacker is at the same level as the target, this could typically reach the corrosive stack limit of five and produce more than 100 ticks of damage bound to the target.

So my wild guess that six sub-clouds were deployed is clearly wrong. I suppose we can imagine that the cloud is a hostile gun that shoots 24 times. Each attack can cause an elemental DoT depending on the target’s resistance. An alkaline shield would grant immunity to the caustic DoT, but the wearer would suffer the “bullet” damage.
