StEvies: When you place your coronas... don't put them smack in the middle of a boss room, and don't put them on the very edge of a large room either. It's hard to see them on the far edges, and easy to accidentally run into them in the middle. Between the middle and edge is a better place. (By the campfire (on a small map) usually works well if there is one.)
+ If somebody asks for a corona, and your corona's on cooldown: say what remainder on the cooldown is. You can easily see it (and all your other spell cooldowns) by pressing the [ALT] button.
Kai: Fighting Keaghan: You can help the people who've been summoned to destroy the statue with your long-ranged attacks! Please do! (Don't forget to watch your back. Keaghan likes to sneak up on people breaking his dragon statues.)
Siglint: That old wive's ditty about lightning "never striking in the same place twice"? Nope!
Siglint Lightning says hi with it overlaping 4+ times at once, and then 5+ the next!
