Gas cloud's poison and detonations

how does this work if I poison a target with gas arrow and then detonate the gas?

does the poison remain on the target for its default duration?

if I don't detonate the gas, is the poison reapplied periodically during the gas duration? or is it pointless to keep the gas on single target for its entire duration?

if poison duration is less than cloud duration, can one cloud poison the same target multiple times?

Gas clouds reapply poison at your attack rate. In other words, cloud is 'hitting' mobs with your attack speed, applying poison with each 'hit'. Thus, it does reapply poison while it(cloud) lasts or stacks multiple poisons if there is a such option.

Cloud poisons target for default duration, which is affected by any poison duration modifiers you have. Pretty much same as regular poisons from hits.

>cloud is 'hitting' mobs with your attack speed
You mean the cloud has its own "hit" (reapply) speed, right ? (it doesn't matter if we can change the ratio or not, for now.)
