Alr gonna keep it short and sweet for a new exotic i personally would find pretty cool to have in the game as a exotic with its 3 variants for each class or potentially given to warlocks or titans for just the original name concept "Radiant crown" if its better suited as a class exclusive
This is a exotic helmet that gives extra functionality to weapons made by the traveler named "weapons of hope"
lets start with the exotic perk:
Hope into action
Apaun healing an ally or hitting a final blow with a weapon of hope, all ability's regenerate 30% faster for 3 seconds and grant Travelers gift buffing hope weapons damage and Noble rounds healing by 15%
now to what falls into this catagory namely weapons made with the travelers light or outright made BY the traveler
Weapons of hope:
Lumina
Hawkmoon
Travelers Chosen
Ergo Sum
