I'm making a pet phoenix concept.
Considering some characteristics.
1. If a pet dies, egg returns.
2. Grow again.
3. Fire attacks. Light in the darkness.

More comments please.

Some extras:
1. Lose hunger (or another) for growing pet, lose sanity if it dies
2. Maybe if the player leaves the combat and runs off, pet stops fighting and follows player
3. Feeding the Phoenix something increases the area it lights, increases the chances of a forest fire if trees are nearby
4. Pets presence gives a very small sanity buff

Not all my ideas, just the good ones I've seen people say and one of mine.

Ryuu, they are very good idea. who are the others?
anyway, I plan to run the first one. Then plan on going the extra.
now, I've built this thing.
Phoenix transformed into seven levels. If the phoenix dies and returns to the previous step.

how about this?

Well it depends, if it goes back one stage the hunger cost could be higher or it can go right back to first stage and cost same hunger, I think back to first stage will make people look after it better and make it easier to bring back if it dies. Just my opinion.

I hope the others come and post their ideas for the pet.

왠지 연꽃송이를 닮았네요.
윌로우의 코드를 조금 바꿔서 불 속에 있으면 체력이 차는 특성이 있었음 합니다.
덧, 제주도님이 대사 작업해두신걸 봤는데 좀 많이... 아쉬운 부분이 많네요.

It looks like a lotus bloom :)
I hope that it has characteristic which regens health on fire. it can be coded by changing little bit Willow's code.

Relating Phoenix with fire is common error in Korea because of it's pronounce. (although it represents the Sun)
그러니까 불사조할때 불이 그 불(fire)가 아니고 아닐 불 이다 말이죠...
I suggest phoenix drops its feather rarely, and it can be used to revive player or other entity.
Dividing seven levels is a plain idea. it is used in WX-78 and other mod characters.
As a parody of Starcraft2, it can use stun( or Airbon) ability at day(using sunray!).

goldlight님 제게는 그냥 한글로 말씀하셔도 되요. 단지 다른 분들에게 의견을 같이 전하시려는 거라면 상관 없구요 ㅎㅎ.. 불사조라는 이름은 별 생각없이 "죽지않는 스몰버드를 만들어야 겠어!" 라는 취지로 시작했습니다 ^^ 말씀대로 죽는 않는 불의 의미는 맞습니다만, 비교적 불사조를 묘사할때는 불에서 태어나거나 불처럼 빛나는 새의 모습으로 묘사하죠..그래서 불이나 불사나 모두 다 잘 어울리는 것 같습니다.위에 류 키츠네 님이 말씀하신대로 모든 단계에서 죽으면 알이 되는게 좋을지 의견 좀 주세요. 지금은 절충해서 4단계까지는 알이 되고 5~7단계는 전 단계로 바뀌게 하는 건 어떨까 합니다.

Was just Thinking, is it possible for a pet to equip items like a player, then you could make it stronger without a levelling system, and have unique craftable items, maybe using GoldLight's idea of the Phoenix feather and potentially other items, like the shaved Musha hair idea i had for the beard/hair.

If pets can't could still use items for Musha's own items, like some Phoenix Armour, a fur hat and stuff like that.

i don't know how to make a pet items.
i can draw a short time, seven different aspects of Phoenix. but lua script is very hard for me. If you know the modified code, let me know.

inst:AddComponent("inventoryitem")
just this code..hah. very fun. but still lua script is difficult for me.

I am currently developing a phoenix.
