OK this looks grim.
As Gash I am rubbish against grenades (I do magical threats). I think the best think for me to do is:
1: Emergency first aid anyone alive
2: Get the dead and wounded out
If you want me to anything else just yell an order.

Invisible castle is down for me...so I am resorting to good old fashioned d6s
Initiative: I'll basically be going last on about 7 this round and 10 + 4 =14(6, 6, 5, 5, 4, 2, 2, 2, 1, 1) next round
Summoning force 6 task spirit: 6, 6, 5, 5, 5, 5, 3, 3, 3, 2, ,2 1. 6 successes
Its resistance: 5, 4, 4, 2, 2, 1
Drain: 4: 1 rule
Result: Services 5
Optional powers: First aid, Concealment
Services requested: countermagic and first aid (so far).
Next round if I can I will triage: i.e. use first aid to see who will benefit from stabilisation. Since I am not using the first aid kit, thats just: 3 successes (5, 5, 5, 4, 4, 3, 3, 2, 2, 1), looking at the two wounded by blades, and the one thrown in the air.
