Candle
Since it was such a close vote between Templar and Candle, I've now added the Candle as a rare light tower.I'm still unsure if the 2 range on this tower is better than the original 1 range. Definitely need to do a few more test runs with this guy. The burning damage over time was not added, instead candle deals more damage against air. The burning DoT is something I have in mind for the next rare tower (Phoenix).
Thanks @t4c1 for your idea!
