Yeti in the Grove

Kill 10 Forest Yeti in the Hills and report to Bosi Brainiac.

Who's there?! Ah, friends? Phew, we... I was so scared.
We pitched camp, left Silvia to look after it and went on a scouting mission. We've never seen forests like this! Trees! Grass! And all this after Siveria! We were watching birdies and didn't even notice going into a clearing full of those damned yiti... yetiti... yeeeti... Those monsters! We ran as hard as we could, obviously. And now we... I am sitting here, wondering where my brothers have gone, whether or not they are alive?
Oh, you're already searching for them? Thanks! Well, help get me out of here! We are not the worst psionicists, honest... false modesty aside. But only when we are together! Alone I'm but a single mouthful for those yetiti... monsters! Why don't you distract them by killing a dozen or so? That'll clear the way for me to make a run for it! Can you do that?

If we hadn't dispersed, we would've scorched those furry beasts' brains right out! But alone I can't even think straight. I start a thought, but there is nobody to continue it.

Thank you! I'm off! Go and find my brothers, please. Let's meet back in the settlement and talk there.
