The Turret

Turret is the main defensive structure in Borderlands, each side has a total of 12 turrets placed along three lanes, 4 on each lane. The middle turret on the lane is the strongest, outer turrets are less strong and arsenal turrets are least strong mainly because 2 turrets are defending a ramp. Turret will reveal stealth and attack any hostile unit in its sight, except wards (from shop and extra talents). Attack priority
 * Enemy hero who dealt damage/ is going to deal damage to an allied hero.
 * Enemy melee/ranged minions, summoned unit.
 * Enemy hero in range.
 * Enemy siege minions.

(Turret will immediately change its target if a higher priority target moves in its range, instead of changing target after killing the previous one.)
