Gold golem

It can be crafted by 2 blocks of gold and on the top a torch

It can be of four varieties

one by redstone torch which spawn with a torch in colour of white ,this torch can be kept in redstone setup and when redstone is given to golem the white torch will turn into red stone torch if you want to reverse click on it torch and it will give you back your redstone with the torch returning 

Second with normal torch this help us in mining where we keep torch every where but it only gives light upto 10 blocks And for every 5 minutes its brightness will decrease and we need to give it coal or else it will eventually become statue If the torch on the head touch water then torch will extinguish giving us coal and will become statue if you need it again just use coal . Same applies for redstone golem but redstone is used in place of coal

Third with the copper torch this will help us to explore ocean as the torch would not extinguish in this case and give us better vision in ocean but it only gives light upto 6 blocks

And in nether piglins will round up near the three varieties of this golem and will become hostile to it but in return they will give 4 random things 

And fourth variety includes a soul torche on the golem and this will help us in nether though it has sufficient light it may helps us in some closed structures and in mining it won't be attacked by piglins and performance the role of iron golem by attacking the hostile mobs who attacked the player
