Tanner smiles as he see the gnoll cleric duck under his swooping black dragon. But as he sees the gnoll cleric recognize it as an illusion and tell the others, Tanner realizes that they've seen through the illusion and he needs to find another tactic.

Looking to make sure that there's still enough room between the gnolls at the top of the hill and his comrades climbing up it, Tanner will cast Sleep on as many of the gnolls as he can, especially the archers who are aiming at Blade, hoping to buy his comrades time to get to the top and engage the hairy dog creatures. He'll try NOT to include the cleric in the spell's radius, knowing that he would have the best chance of shrugging it off, instead focusing on the archers and other gnolls waiting above.

Humming a soft lullaby, Tanner conjures up the arcane power and sends it towards the gnolls on the hill.
A tall, gangly human youth looks at you, his questioning green eyes filled with the energy and enthusiasm of youth. Clad in a fine chain shirt with a buckler emblazoned with crossed lute and sword, he wears an Elven rapier at his side and a rustic lute over his shoulder.
