Hey Arlorians,
Today i come with an interesting idea which actually bless the game fun . Blending 2 or more items into a single item or specific ability ( not skills, ability like adding 4th gem slot on an arcane rarity item).
 
This will be a tough job to get blend box that allows blend items, there maybe a quest like arcane parchments

 
Just like craft blend need ingredients to craft the subject. Blend box is actually a Box inside your inventory chests side, blend box contains 8 slots which can either be used to store items and join them together to a single item

 
 
2Elixirs can be combined and the first elixir will get advantage of 5extra minutes and if we join respec and ankh kits it will give more ankhs/respec scrolls. Like
A. 30% damage elixir + 25% luck elixir= Blended Elixir of Damage grats 30% damage for mins and 25% luck for 30mins
B. 25%luck+25%xp elixir=Blended Elixir of luck 25%luck for 35mins+25%xp for30min
C. 25Ankh kit+ 5Respec kit= Blended Ankhs kit 30ankhs plus 5respec scrolls
D. 5 Respec scrolls+ 25Ankhs kit= 6Respec+25Ankhs kit
 
It will allow Combine some gems together. And jewels together ( gems can't be combined with jewels)
A. Blood gem + Fire gem = Tarlok Rage gem
B. Fire gem + Blood gem = 3dex+2str (if grand 5+3) or depending on level scales
C. Jewel one + jewel second (must start from weak) First jewel will give full stats second will give 2 stairs less stats like weak fury + weak finesse= 3str+1dex noble mind+ noble fury= 8int+6str
 
There are many vanities what can have combo with other vanities No need examples
 
There may be some glitches and secretly joinable items which may have stats buff on pvp or add something additional over an equipment So this will be a deep million combo research with many items
