Currently you cannot use more than one ability based off Starfall per map if you wish for each of the abilities to have different visual effects. This has directly affected a project of mine and though it may only be considered a minor issue it’s still something that didn’t need changing with reforged and I hope blizzard is aware of this and fixes the issue at some point.
Are there similar abilities which can be indirectly triggered which you can substitute?
Imperfect substitutions are Rain of Fire, Blizzard, or perhaps even a manually triggered Starfall ability.
Blizzard seems to work the best but this issue should still be addressed by Blizzard(ent)
