Ingtas uses the mistake one of the sligs made and attacks him.

Spoiler

Touch attack: (d20+8)[8](16)
If the touch attack is successful then Strength check to trip: (d20+15)[13](28) (+4 large, +4 Improved trip, +5 Str, +2 from Mekilot Sap)

If I don't manage to trip it then counter trip when the slig tries to trip me in return (d20+15)[14](29).

If I trip the slig then attack roll: (d20+12)[3](15) and damage: (4d6+7)[2][3][2][5](19) (I think that 2d8 grows to 4d6 but I'm not sure. If I made a mistake feel free to re roll for me this time).
