Taxes Domain

Clerics of this domain ascribe literally to the belief that the only two forces in mortal like that matter, are death and taxes, and that an individuals wealth is a measure of their devotion to their deities. Their places of worship are lined with gold, and their clergy are known to exact tithes and tributes. Most churches of the taxes domain are seen more as banks than true places of worship, where priests of this domain offer loans, and collect on such loans with the vehemance of zealots. 

Art of the Deal

When you choose this domain at 1st level you gain proficiency in the persuasion skill, and may add your wisdom modifier to any persuasion check made to try to form a deal, gain a discount, or bribe. 

In addition, you may substitute the material components for spells with half the material components cost in coins.

Channel Divinity: Glittering Influence.

Starting at 2nd level, you can use your Channel Divinity to buy out the loyalties of others.

As an action, you present your holy symbol, and one creature of your choice with that is within 30 feet of you must make a Wisdom saving throw, provided that the creature can see or hear you. If the creature fails its saving throw, it is charmed for 1 minute unless it's intelligence is below 4. 

A creature charmed in this way will reguard you as friendly, must use its movement to stay as close to you as possible, and will fight to defend you against hostile enemies it can see, so long as you offer up a gold piece each turn per cleric level to it. (This is a free action and does not require a free hand.) This gold vanishes if the creature is slain or robbed. It will also follow verbal instructions so long as they are not directly harmful to it and these instructions do not move it away from you. The DM decides how the creature will defend you based on its natural behaviours.

 

Death and Taxes

Starting at 6th level, whenever you cast a spell while in combat with an enemy, two gold coins scatter on the ground around you within your space for each level of the spell. (It is up to the DM's discression if this feature activates, it may not if a combat is being used to intentionally produce gold against a non threatening opponent, or it is a friendly spar.)

In addition, you may as an action speak a prayer and offer up 10 gold pieces per spell slot level to regain a spell slot. You may use this ability a number of times equal to your proficiency bonus, and regain all uses after a long rest. 

Potent Spellcasting

Starting at 8th level, you add your Wisdom modifier to the damage you deal with any cleric cantrip.

Armor of Midas

At 17th level, your armor glitters with jewels and the gleam of gold. All enemies have disadvantage on attack rolls to hit you. In addition, you gain proficiency in heavy armor, and do not require strength to retain your full mobility while wearing it.
