Need help with creating a spell that fires projectiles in a cone shape and then damages units. It's something similar to DoTA's Troll Warlord's ranged version of whirling axes. Whirling axes basically fires axe projectiles in a cone shape AoE and damages units.
As Slapshot said, you can use a breath, carrion swarm or maybe shockwave... If what you want is actualy an "axe wave" I think the simplest soluction would be using the Fan of Knives missile, it's a cool dagger throw in cone shape but I don't know if it suits your needs.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
