Character Enchantments.

Right now, I have two characters. One I play mostly (min/maxing etc) and one I play with my much lower friends. 

There is zero need for me to re-run the game and create another character. Why? Because I already have multiple loadouts. For example:

If i'm rushing runs for unique loot I equip:

2x Ghost cloak

1x Boots

1x Cursed Axe

Once I get to the boss I equip:

2x Mushroom

1x Iron skin

1x Moon daggers (..I know.. I'm working on it)

If I want to play with others, I have a plevel 108 suns grace (I could also equip the saberwing). When I play alone, however, I just equip my solo weapon (as shown above).

However, If we could spend enchantment points on character based improvements (3% bonus defense for like 3enchantment points etc - there could be a whole power-tree) - then not only would end-game stay interesting, but people would have more reason to create different characters? 

Finally, to complete the game with one character you already have to finish the entire base-map three times. This would add some variety to the runs!
