If been playing the games for some time now and i came up with some ideas for the game.
Dark witch
The Dark witch will work similar as the dark forge except it creates potions instead of items.
Set transmutation
Transmuting 4 steak, 4 daggers etc. will create a higher quality one.
Splash potions
Giving a tower a potion will add the effect to all towers within X range.
Stat and skill points
This is quite big and will need a lot of careful balancing
It splits stat and skill points
Stat points will boost the damage, attack speed, item find, experience etc and don't have a max lvl(or maybe not to stop being OP)
Skill points are for skills like more waves etc.
Lvl cap skill
A skill that increases the max lvl cap of (all) other skills so they can be higher than 10
Not all of these work very well but still some of them can become really great
although they might need some more tweaking.
