Some fields have nice hover tips and some don't. Just the way it goes. Maybe a magic intern fairy will put the rest of them in a future patch.
All and all depends on what you want to fire and how you want it to to resolve. However, a damage response proc behavior... this could be useful for my Protoss Phantoms' phase out. (they work kinda like faerie dragons from war 3, but can move while out of phase.) Presently, they fire off the ability as soon as they enter combat (provided it is not on CD) and then fall out of their "phase shift" style ability at a random interval of 3-5 sec. However, putting it on an ability allows a player to hit it prior to entering combat to close ground with the target as well. Still, a damage response would probably smooth out the effects a bit better than an "enters combat" validator. Maybe I'll scrap the pre-pop to make them less micro-intensive. On the other hand, allowing a player to disable the auto cast of it could make the micro more fun for micro junkies. Kinda like burrowing hurt roaches. All depends on "beta" response. When I get there. Stupid actors, making art all modular. XD But, I suppose it beats scanning raw code like in "the good old days" that never existed. Thanks for a second opinion doc. I got no money, you take gems?
