Does using the same base ability on two dummy spells that add a buff to a unit cancel the other buff? For example, if I make two dummy spells that just add a buff to the target, I'll just name them Buff1 and Buff2. Now, if I cast Buff1 on a target and then a few seconds later(while Buff1 is still on the target) cast Buff2 will Buff1 go away? Or is it just the icon for it? Or does it work fine? Well, if adding Buff2 over Buff1 makes Buff1 undetectable by triggers, is there any way around this? Maybe adding invisible abilities to the unit rather than buffs? |
