Al-Khazad is halfway down the rocky wall when everyone hears a shout from the top. As you look upwards, a shower of gravel and pointy pebbles fall on you.
Jagra: As you started to move to have a better view of the surroundings, you noticed the floor is quite treacherous. In the shadow of the mountain, the wet tiny rocks rest precariously, and you discover that simply making then slide under your feet and falling on you back. The disturbed floor slides under you, and it provokes a chain reaction. Soon all the slope comes alive, rolling down and carrying you to the cliff.
Down your situation isn´t a lot better. Next to the wall you can avoid most of the falling debris, but still some of them hit and wound you.
[Al-Khazad and Menghil suffer no damage thanks to the damned Evasion, Amira and Akeeta are wounded for 6 hit points. Jagra is prone and will fall the next round.]
