Blessing-system with heavy drawbacks to strengthen niches and ease solo-play

SanguineSkaven

Blessings are Buffs-Debuff combinations that can be aquired or changed at a shrine. Only 1 Blessing can be active at a time, and as each comes with signifcant Disadvantages they are highly situational and in most situations you do not want to have any blessing. Their purpose is to strengthen niches without destroying the normal game balance.

All values are merely for demonstration purposes and require actual balancing.
Blessings are aligned to the 7 heavenly virtues for meme-reasons.

Blessing of Humility
Reduce dmg taken by 1 star or below enemys by 35%. Decrease dmg dealt to 2 stars or above by 50%.
Reasoning: This blessing helps small groups with aoe farming, or increase fault-tolerance for farming solo.

Blessing of Chastity
Gain passive health regen (part flat, part percentual), even in combat. Reduce healing received by 90%.
Reasoning: This blessing helps players that do not have access to healing in their kit or their party. The flat part makes if specifically strong in the early game, easing in new players.

Blessing of Patience
Gain more xp based on how much dmg you dealt to the enemy, up to 50%. decrease dmg dealt by the player 20%.
Reasoning: This blessing can help in solo-farming spots, especially where the respawn rate of enemys is the limiting factor.

Blessing of Temperance
Gain passive mana regeneration. All your skills can only hit 1 target.
Reasoning: This blessing allows you to build strongly spell-reliant single-target Builds.

Blessing of Diligence
increase sprintspeed by 10%, decrease stamina drain while sprinting by 50%. increase stamina drain for dodging and blocking by 100%
Reasoning: This blessing is not really viable for any build focusing around combat, but gives both speed advantages and a safety feature for gatherers.
as long as the gatherer is not cc-ed or bursted, he can use this blessing to simply run for his live, most likely outrunning his oppenent.

Blessing of Kindness
Reduce damage taken by players by 50%. You can no longer flag for PvP. You are unable to damage players, and can only heal green players.
Reasoning: A blessing providing protection for those who refuse to take up their arms against others

Blessing of Charity
Increase material yields significantly. All materials gathered with this trait will drop on death and can not be traded until they are carried inside of a node.
Reasoning: High Risk, High Rewards.


Variations:
Craftable offerings allow you to pick more than 1 blessing
Religious nodes allow you to pick more than 1 blessing
Religious nodes could strengthen the blessing
depending of the faith of the character he could aquire blessing/curses for the seven deadly sins instead
blessings/curses could be bound to the actual gods instead

I think blessings like this given out by the ranking priests (top 10% of members) of Religions which can be given only to other members. The priests have 3 options, 2 that the top member of the religion (the Pope) picks, and one which is fixed and thematic to the religions lore. Let the blessing last several hours.
