Morkeleb sees Jar take a grievous wound and go down. The goliath looks to be in bad shape. Reluctantly stepping back a bit from the dastardly dwarves, but still holding his sword and shield between him and the enemy, he crouches a bit to reach down behind him and put his hand on Jar's head. Morkeleb's eyes glow with golden light as he boldly pronounces, "Jar, your fight here is not done! Rise and help us win the day!"

Holy energy flows from Morkeleb into Jar, closing his wounds and breathing vitality back into him.

Now that he's out of reach of immediate weapon strikes, he lead duergar watches Morkeleb's healing and grumbles, "That won't do." He then waves his arms and says to the paladin, "This is happening because your strong friend there was trying to fit in some extra strength training to surpass you. You oughta get your own squats in so you can stay top dog." Morkeleb, make a DC 12 WIS Save or feel compelled to obey the Suggestion.

(Jar, you still get a turn on a failed save. It uses your reaction for the attack, but you can take your turn normally beyond that)

(Jar Failed big time his INT save. I was not sure, but I thought I was now under the effect ("... exert his mind mastery on Jar.") of something the lead duergar did to him)

(Right. The effect is that you use your reaction to attack an adjacent ally. You can still take the rest of your turn normally)
