Does anybody know how conflagation work?

Does the wizard passive conflagration work on allies? With other words, can it be ran in a zwiz setup to increase crit chance for your allies? I can’t find any information about this topic anywhere else on the internet. All I know from reading the passive is that nothing implies that it shouldn’t affect your allies as well. Some passives tell you in the discription that they “don’t apply to allies”. In the case of conflagation the discription doesn’t tell you that it shouldn’t affect allies. Therefore I’m assuming it affects allies aswell but I would like more information on the topic. Currently no Zwiz builds I find runs fire dmg together with conflagation which makes me really confused because on paper it looks like a really strong support tool “if” it does indeed work on allies
