In Goblin, the Goblin Commander orders the front man to hold his guard while everyone readies themselves.
Mak stands ready to do whatever harm works, as the foremost goblin raises a tower shield in front of the group. The goblins right behind him sink up their initiative (refocusing for 20), and the last goblin fighter in line hands a Heavy Crossbow, and 8 bolts to the goblin behind the one holding the tower shield.
All other goblins refocus this round.
Regis and Khala move forwards, Khala creates an area of grease. All three standing goblins fall down, into a mess of trouble.
I'm assuming Brawn doesn't see the need to cast create water, with Grease already active, and instead refocuses for next round.
New Initiatives:
Mak - 20
Regis - 10
Khala - 7
Brawn - 19
Goblins - 21
Goblin Fighters - 20
Goblin Commander - 25
Halfling Cleric - 19
