This adds 2 new treasure items. 1 is the king mask and 2 is the elixirs. The king mask is just a really beefed out helmet. There are 1 elixirs, 1 is the strength elixir that is just a very buffed strength potion, and the second elixir is just a really buffed healing potion. (These new treasure items can not be crafted and can only found in the new temples). This revamps jungle temples adding a whole new underground part. This mod does not get rid of the old jungle temples so the new ones from this mod will be with the old ones. This mod also adds rubies, only in the new temples can you find "Ruby fragments", 9 of these can be crafted be crafted into a normal "Ruby", and 9 of the normal rubies can be crafted into a "Block of Ruby" for an achievement. Also 1 ruby, 2 iron and 2 sticks can be used to make a "Ruby staff", which is just a really OP bow with infinity ammo. And finally There is a new music disk that is C418's "Door". There is a little more, but it is mostly self explanatory.
