Lightning Rod Feat

You learn to store lightning energy within your body. You gain the following benefits:

Prerequisite: 4th level, Wildling

• Ability Score Increase. Increase your Strength, Consitution, or Intelligence ability score by 1, to a maximum of 20.
• Lightning Draw. When a creature within 10 feet of you takes lightning damage, as a reaction you can redirect that damage to yourself.
• You gain the Lightning Burst special attack (below).

Lightning Burst - Active Ability (Attack, Supernatural)

• When you take the Attack action on your turn, you can replace one attack by unleashing lightning that blasts all targets of your choice within 10 feet of you. Each target must make a Dexterity saving throw. On failure, they take 2d6 lightning damage. On success they take half as much damage. The lightning damage increases by 1d6 each time your proficiency bonus increases.
• Once you use this feature, you cannot use it again until you complete a short or long rest.

Mystic Path Feat Save DC:

• Any time a mystic path feat requires an ability score modifier for spell attacks or saving throws, use Constitution as the modifier. The DC is calculated as 8 + your Constitution modifier + your proficiency bonus.
• If your class grants you a spellcasting feature, you can use that ability modifier for calculating spell attack rolls and the DC instead of Constitution.
