Two stoo shrooms roll around the corner at high speed, their “tires” very quiet on the smooth floor.  They are closing to melee distance in an eyeblink.

Initiative

• Shrooms 0 = automatic win
• Ragnor 8 + 2 = 10
• Arvak 6 + 1 = 7, tie-breaker 7
• Phallon 5 + 2 = 7, tie-breaker 4

The planar portal shimmers, it has another 30 seconds.

What do you do?  (Reminder: you can elect to dodge, or tell me “I dodge if I am attacked first, otherwise I do this…”)
