Weapons with the bosses can get if they win again in eclipse mode!
To enter in eclipse mode - you need to click on the top right of the sun on a map (switching option eclipse you get a little passing game on the storyline).
After the pass of the guard and the boss, you'll get his weapon!
Keep in mind that in eclipse mode, all the fights will be much more difficult, it will require the best equipment for the battlefield. To return to normal mode, click adventures in the sun again.
Please note, if you use the old cracked conservation, "Eclipse" mode will not work properly with the result that further passage is not possible. Play fair.
