whoa i just had the best spell idea come out of nowhere a few seconds ago, i needed to post it to not forget it, and since you're a triggerer i thought i'd drop an idea:
a magnetic missile or net type thing, you aim it, cast it and anyone close to it's path gets dragged with it until it blows up (missile), or when it stops, the unit slowly recovers speed, 90% > 80% > 70%, etc. (net). this isn't a request btw, just idea if u need one.
