I have created this puzzle quite some time ago in the style of the - then still ongoing - CiSRA puzzle competition, but very heavily leaning on elements of the computer game Guild Wars 2.
A couple of notes regarding the puzzle
- the puzzle consists only of the picture below
- the solution is a single word or short phrase
- the knowledge tag refers to the fact that this puzzle's theme is heavily influenced by the Guild Wars game. Since I don't expect a lot of people here to know it, I'm including some initial hints below that would be obvious to players of the game. All necessary information can be found online (mostly on the wiki) without ever having played the game.
Hint 0 (for people who don't know Guild Wars 2)
The puzzle shows the in-game symbols of various crafting materials and sigils that are part of the game
Hint 1
Players of the game often will refer to specific grades of a material by 'tier N'. E.g. T5 wood; T3 Blood, ...
Hint 2
Think exaggerated, when trying to decipher the first set of clues
Edit: I'll start adding more hints over time
