D&D 5E - Legend of Zelda inspired campaign

killer chickens is a must
and definitely not going to go the same encounters it is more of a draw inspiration from for the story which all my players already know. I also know i am not allowed to have a water temple at all.

not sure about the races/monsters but the bosses definitely i would just have to get really good at building monsters may even give an obvious weakness that if the players notice they can exploit

what items if any do you guys think should be ported for magic items?

should it be medallions, crystals, pendants, rings, pearls or fragments that the party should dungeon to collect to help kill the big bad guy?
