Ranger Skully

About
For every dungeon, there will be a Ranger Skully. The higher level dungeon you raid, the harder it will be because the amount of damage and health will increase. This does about 7 to 9 damage, it shoots faster than the Skully Sniper but does lesser damage than the Skully sniper.

Tips
This one is relatively easy, but if you are a beginner and you are having troubles, you can use this method. This works for the other dungeons as well. Firstly, you will need a shield and a gun. Hold the shield, once it fires at you, fire back or use a weapon to slash it and change back to the shield and remember to hold R. Repeat the process and it kill the Ranger Skully.
