Never played a ttrpg but this homebrew stuff seems fun

Divinely Chosen
Those who walk the path of the Divinely Chosen place their faith in a singular, all-powerful creator, one of law and order. Whether that being is truly listening is a matter of faith, but the Chosen believe their prayers channel holy power into the world.
Restrictions
They can only wield blunt weapons and small bladed weapons.
The Chosen may only wear light armour (such as leather or padded).

Lone Prayer
Once per turn, the character may spend a full round praying instead of taking other actions. On their next turn, they may roll a d20 and apply the result to a chosen target within 20 feet.

The caster may choose to invoke the inverse of the prayer to cause harmful effects.

The caster may add or subtract their wisdom bonus + half of their level (rounded down) to the roll.

This action can only be used during combat.

1-5
Nothing happens.
6-8
Target gains +1 to their next attack roll. (-1 if inverse)
9-11
Target gains +1 to their next damage roll. (-1 if inverse)
12-14
Target gains +1 AC vs the next attack made against them. (or suffer –1 AC if inverse).
15
Restore 1HP to target (or take 1 damage if inverse).
16-18
Restore 1d4–1 HP to target (minimum 1). (or take same damage if inverse)
19
Restore 1d6 HP (or take 1d6 damage if inverse).
20
Roll twice and apply both results to the same target.


If the result of the initial prayer was greater than 5, the caster may choose to test their faith further. They may roll 1d20 again to determine how many targets the prayer affects. Targets must be within 20 feet.

1-5
The more demanding prayer is unanswered. The original effect is lost.
5-10
The effect applies only to the original target.
11-15
The effect applies to two targets.
16-18
The effect applies to three targets.
19-20
The caster may choose to apply the effect to any number of targets within range. Each target may receive either the normal or inverse version (caster's choice per target).
