I just had a good idea and I think you should consider. I've thought about this a lot.
What if we added ICE CREAM to the game. I think it would be so cool to be making different flavors of ice cream. My idea is that players cant eat the ice cream but you can feed it to tamed mammoths to unlock "True Mode". A "True Mode" mammoth is able to fly over palisades and brick walls and you can attack people with bows from above. You can also fly over land really fast. I think this would add a lot to the siege system if we did this.
Ice cream would be made with an ice cream maker which is built with wood, wrought iron, and lots of gold. Also you can put rare items into ice cream so when you feed it to mammoth it becomes even more "True Mode" than normal. Like if you put a bear cape inside the ice cream it would unlock "Level 3 True Mode" which allowed you to fly around quicker or maybe even have strong mammoth attacks like spraying lava with its trunk or something. Then strong players could have a new end game content. Maybe "Level 5 True Mode" mammoth could be sacrificed to end the world.
Also I was thinking that when you kill a "True Mode" mammoth 2 hours after its been fed ice cream then you get a "privateer" debuff. this debuff would decrease all stats by %50 but if you had it you could craft things with twice the speed, that way it is balanced. If someone with "privateer" debuff is killed, the killer gains "master" buff which unlocks a temporary skill that costs 20,00 lp. The skill would be called "Cold Hands" and it would allow you to create ice cream with twice the effectiveness. Also, if you had "Cold Hands" skill you can turn anyone you touch into ice. That ice could then be used to create a "Mammoth Ice Token". If you have 500 Mammoth Ice Token you can keep the mammoth in True Mode permanently. Only mammoths that are level 1-3 true mode can be kept permanent however to avoid overpowered (note: I still don't know what the different levels of True Mode would do but the higher it is the more powerful). Also, if a True Mode Mammoth that is locked in true mode is killed by a player with charisma and psyche above 38, the player who tamed that mammoth dies as well. To avoid confusion, a new skill called "Mammoth Hunter" would be available for 2,000 lp that would allow you to craft a Grey Compass using beautiful dreams, a stick, and iron. You can use the grey compass to identify the owner of the mammoth. Also, "Mammoth Hunter" unlocks a new craftable item called Winter Katana. If you kill a Mammoth Trainer by killing his/her mammoth, a "WInter Spirit" will appear in the corpses inventory which you can then loot for yourself. You can then craft the Winter Katana with 4 Winter Spirits and 10 Silver. Once you craft the WInter Katana, a new stat will be inlocked called "Zen" which starts at 0. You can increase Zen by killing Trolls. Zen effects the damage of the Winter Sword.
Also, the player with the most Zen on the server will be able to fly without a True Mode mammoth. They will also have the ability to kill any player instantly using the console so they are basically invincible.
I think this would be good idea and it sounds pretty balanced but it might need improvements. Please post thoughts. I hope you consider Jorb.
