Suggestion:
Champ skull trade in barrel(s).
Part 1:
Trade in any combination of (25) champ skulls for a Valor Crown. This crown can be used to activate a champion spawn of your choice at any completed champion alter.
Part 2:
Trade in 10 standard Valor Crowns for a "Grand Valor Crown" with awesome stats. This would require defeating 250 champions spawns. Quite a feat.
OR
Part 2 alternative:
Trade in (50) skulls of greed for a Baracoon Crown, (50) skull of death for a Niera Crown, etc. Collect all 6 crowns and trade in for a "Grand Champion Crown". This crown is a levelable helmet and can be used to teleport you to a special incredibly difficult champ spawn area with rare item drops including gear, resources, and deco. Putting use to "Part 1" can help players obtain specific types of skulls needed for trade in.
Consider using "Part 2 alternative" with the mini champs in Ter Mur instead of the standard champ spawns as they already have plenty of incentive.
Some side notes:
- I think this would bring some value to the player economy.
- Consider dropping more than one skull per spawn depending on number of players dealing damage to the champion. Max out at 4 skull drops. this would encourage group hunting.
- I would suggest reducing the respawn time just slightly, as well as the amount of gold dropped. This gold loss to the players can be made up with the increased value of the champion skull and will avoid gold inflation.
cool ideas!
