So,suggestion I wanted to write.
I can't remember if I already written it,but I have feeling I written in past.
Its quite big,complex and may seem out of place,but I still want to share.
Altar to Spirits
Act of respect to spirits of your ancestors,to perform requires Pyre,Incense Burner and one four block runestone pillar(or runewood pillar, depending on spirits).
Upon activation changes chiseled runestone(or runewood) to a sign of spirit u are praying to with green particles flying around and animation of rearranging top block to form said signs.
Once u prayed,u are linked to this exact stone and anyone who breaks it,will be cursed by spirits depending on their mastery,even you(if in future u will be able to get cleansed from Untrue Pacifist advancement,than for this feature there should also be such advancment and also way to cleanse curse of ancestors).
Linking it to yourself will unlock pleasing,which is way u gain power from your ancestors,by giving them gifts.
If u want to get their blessing,u should gift them their related item every single day, otherwise they won't give u any blessing.
Blessing consist of passive part and part that may be activated once per day.So,spirit houses:
1.Warriors Spirit.
Warriors grant their worshipers
Passive: Ancestors see your ability to fight and are proud,they grant u regeneration 1 for 5 seconds after u kill mob.
Active:Once per day, ancestors will grant u ability to withstand a fair fight before u gone to spirit realm.If enemy has at least five hearts more max health than you when fight is started(if u hit enemy or enemy hit you)u will be granted with more health (up to 30 heart) and healed to full.
Dedicated gift items:Fried Meat and Honey(tho isn't suiting for mod,I just wanted to make reference to Valhalla,but its can be also either sacrifice of hostile mob,or giving them thier drops,like spider eye,bone rotting flesh etc)
Pilar: Runestone
2.Druids Spirit:
Druids grant their worshipers
Passive:Druids of past see your respect to Nature and prowess in their craft,they increase yield of your crops especially knife drops.
Active:Once per day,your next ritual will work for full night.
Gifts:Wildwood tree growing nearby(u need to grow a new tree every time)
Pillar:Runewood.
