Hello.

I have been trying to build a Td type map.

I have the map and start and time triggers done, now i'm working on the towers.

I want a Multi shot tower for fire,ice,poison and a armor reduc.

Basicly i want to know how to have a tower shoot many targets and have lets say Ice stick to them and slow them down. same with fire to burn and poison to slow/poison and a tower to reduce the targets armor when hit.

I kind of have the abilitys for multi arrows but when i add lets say cold arrows to the buff, it shoots 4 arrows looks like cold arrow effect but doesnt slow targets down. I've tried to add slow and slow poison and burning oil but non seem to work. All that happens is my towers shot 4 arrows with the missle art but have no effects.

I'm stumped.......

Do i need a trigger or something to make my multi towers work with effects?
Any help
thx
