Flash Grenades!
Pixie Dust & Blinkroot -> Flash Powder
Combine flash powder with some wire and a grenade.
Flash grenade. 4-second timer, blinds for 5 seconds and mildly disrupts aim for another 2.5 seconds.
Yes.
Oh,
yes. That could work.
Maybe a mine too. Could be a frag-mine, so to speak.
Some crystal shards for shrapnel, a bit of wire, pressure plate and some iron.
Drop/throw onto ground.
Entity is only visible on the client's team's side.
Step on or step near -> Mine detonates, releasing a small explosion (1/2 grenade's size) & tossing shrapnel in all directions.
All of my want.
