RPG I: The Necromancer's Revenge

So, we dealt with these, what's next? They're probably not alone here. Maybe I should go scout ahead, - said the high druid.

I'm using gating and casting fireball, the troops are attacking...

Curse of Silanna! Where did all these come from? I dodge the flying fireball, it hits the druid and the dryad, and they die. I strike preemptively at the one who threw the fireball, go around to the left, and run into the safe darkness of the dungeon, the last bastion of resistance.
