After completing Legend Mode, Hero Mode will be unlocked. Battles will much harder but better weapons will drop from fallen warriors.
Also, a Second Gold Skulltula will appear on each scenario stages. However, these will only be available in Hard or Hero mode difficulty and for only specific warriors or weapons. There are specific conditions for each Skulltula so make sure to reach the battle conditions first before starting a scenario to know which warrior and weapon to use.
Why does the Caste Keep, keep falling all the time, when i'm trying to kill Ganon Beast? I fail just by: Ganon killing me/ and or: Castle keep falls. DX. Love the game though.
