Gift of Mechanus

General Feat (Prerequisite: Level 4+, lawful alignment)

Through some interaction with the Plane of Law or its citizens, the Modrons, you gain the following benefits.

Ability Score Increase. Increase one ability score of your choice by 1, to a maximum of 20.

Chain of Command. You can channel the hierarchical nature of Modrons to alter damage and healing. When a creature you can see within 60 feet of you rolls to restore Hit Points or deal damage, you can take a Reaction to increase or decrease the type of die to an adjacent die in the hierarchy. The hierarchy is d4, d6, d8, d10, and d12 (a d12 cannot be increased, and a d4 cannot be decreased). You can only increase or decrease a die type by one, and the maximum number of dice you can affect as part of the Reaction equals the modifier of the ability you increased with this feat (minimum of one die).

For example, if your ally within 60 feet of you casts Cure Wounds, and the modifier of the ability you increased with this feat is at least +2, then you can take a Reaction to change the 2d8 used for the healing to 2d10.
