Actions

Skill drain The target must succeed a Wisdom Saving Throw (DC 14) or 1d6 to determine whether STR, DEX, CON, INT, WIS or CHA is affected. The stat gets diminished by 1d4 , which is removed by completing a Long Rest and succeeding a DC 15 Wisdom Saving Throw.
Repulsor The target must succeed a Strength Saving Throw (DC 14) or take 2d6 force damage and be pushed back 20 ft. in a straight line from the Seeker.
Charm (Recharge 5-6) A creature within 30 ft. of the Seeker must succeed a Wisdom Saving Throw (DC 14) or be Charmed until the end of the creature's next turn. While charmed this way, the creature can be forced to attack its allies or spend its movement as the Seeker desires. Every time the target receives damage, it can also repeat this save as well as as the end of its turns.
Skill Barrage (Recharge 5-6) The Seeker releases a powerful blast in a 15 ft. cone, causing all creatures to suffer the effects of a Skill Drain.
