Turtles a little less exciting of an Event Boss as they don't drop a lot of Resources. You'll still pick up plenty of and Research Stones. The level 1 Turtle is easier than a B10 I think, its really easy. The level 2 Turtle is a little stronger than a B11. The level 3 Turtle is a little weaker than a B12 and the level 4 Turtle is about as hard as a B14.
