(Not a Bug) Creeping Death weapon doesn't give mana with "Deadly" upgrade

Weapon “Creeping Death” has upgrade called “Deadly” with description “Give all Allies 2 mana”. I just bought that upgrade and it doesn’t seem to work. I tried with several different decks and classes. Never gives any mana to any of my troops.

I am playing on Android phone.

It works.
You know that you have to cast it first and then the effect triggers?

Yes. I triggered it. All the other weapon upgrades work like they should too.

Shit, I just realized I am mixing mana and magic :see_no_evil: stupid. Should not report bugs after midnight :sweat_smile:
