Elemental effects details question

[Garaj]

Can somebody tell how do elemental effects work? Decay (50% slow) and lightning (10% dmg increase) are already known, but burn, miasma and fusion are not really. Miasma and fusion explosion dmg is unknown, burning dmg is 20% of weapon dmg each sec for 5 seconds. My questions are:
Does burning effect stack with different instances/weapons? For example, if I use laser glove and proc burning multiple times, will dmg timer only reset, or each burning instance will work simultaneously?
Different instances of miasma seem to stack, but how is dmg calculated?
What's dmg of fusion explosion? Do explosions happen for each decay/burning effects application?

Thanks for bringing them up! We'll optimize the tutorial in the future. As for now, I'm glad to answer your questions:

#1:The burning effect cannot be stacked and the highest dmg of burning effect would be in effect first. When multiple stacks are happening, then the higher buring effect damage works first while the lower one is "queuing up". When the first burning effect is running out of time, the second one would be activated. But the duration is shortened since the time to "queue up" is also calculated. In the contrary，if you inflict the effect with the lower damage weapon first, then the higher damage one would overlap the former one, which means the former effect would be terminated earlier than expected.

#2: Miasma's DMG is fixed at certain % of Enemy's max HP (with lower % for Elite and even lower for Boss). And it can be stacked.(9 stacks at most)

#3: When an enemy has been suffering from decay/burning effect beforehand, then explosion can happen when applying the other one. The fusion explosion DMG is related to the triggering shot DMG which set the exploson.
