Some questions:
Can I technically drop out of the event and re-join on a different starting tile?
Now a more serious question:
What do the * mean on Weapon* type artifacts?
Also, which relic type can be obtained with what method? Namely: Common, Rare, Weapon*, Epic, Legendary. Also, are there overlaps between types? (e.g: There are specific Rare and Common items that can be freely picked up just by exploring a tile, but there are Rare items that can be only obtained by opening a chest by a switch.)
You can technically fix your starting tile whenever you want UNTIL you make your first move. Then your starting position is finalized.
The '*' on the Weapon Relics just signifies that it's a unique type of rarity to make it separate from the rest (since otherwise, I would have put the following adjectives (Common, Uncommon, Rare, Epic, and Legendary) to describe the items. But since every element has one weapon, I cut the Uncommon Relic out of the picture, because that adjective always sounds lame.
For the most part, the rarities are separated into 3 categories:
Common/Rare - Can be found by exploring tiles. All of these Relics are out in the open.
Weapon* - Requires Keys, Switches, and/or other unorthodox solutions to obtain. I specifically designed the spots for the Weapons before all other tiles were placed down.
Epic/Legendaries - Found in the center most tiles in protected 'S' chests. Switches are required to open the Epic layer.
Legendaries can only be opened under extreme/unique circumstances.
