According to Thai folk religion,
You can sacrifice jackfruit, pumpkin, crab, fish, chicken, eggs, apple, banana, orange and meat.
Flowers as offerings are acceptable too
I think adding these religious rituals in Lonarpg would increase the social-religious lore of Lonarpg.
Like offering flowers of any kind would temporary provide extra hp, offering fruit will provide temporary extra stamina, meat will increase temporary hunger meter, offering money will increase temporary SUR and offering mutated meat will grant you low moral.
