Ok, now tell me what our heroes do wrong. Our Overlord knew that monsters attack only once. Moreover if you interrupt action sequence of a single monster - you loose the unspent actions.
We tried to pull it out in 3 heroes (Leoric Necro, Avric Disciple and Grisban Berserk) and failed. Maybe we do something wrong with the first move? For our first move we went with Avric and Grisban to stand 2 coridor cells before the water to hit the goblins who finished their move entering the water and Leoric went to loot the first explore point.
Some people say here that right tactics is to rush to the goblins for fatigue and kill them before they move. But movement like this is moving 1 cell for 1 fatigue point? And reaching goblins for only a distant attack requires 4 or 5 movement points. So at best you can hit goblins only with 1 range attack per hero.
And the OL acts the next way: he moves white and red ettin to block the "crossroad". First he moves with red ettin and throws Grisban into water. Then he goes with white ettin to the part of the crossroad where heroes start. And he's already able to reach Leoric with white ettins attack. By playing an additional attack and the critical strike cards Leoric ends up bashed just after the first turn! And no more saving -1 attack aura that could make other two heroes with shields more durable. Then he moves all 4 goblins and shoots a hail to Avric.
The second turn for heroes goes in reviving for Leoric, Avric came closer to the red Ettin and the berserk dwarf used hiss skill to blink to the monk and deal all his remaining blows to the red bad guy. But with 2 defence dices these were barely scratches.
The next turns are also went like:
OL move: Leoric dies from 1 blow from the white ettin, dwarf gets thrown away with red douchebags skill and goblins keep running trough. A bit after leoric also dies from 1 single hit from red ettin with attack dice reroll and 2 power surges.
And that's the way we lost few times. Even the strategy of taking 2 guys with shields and a guy who reduces attack damage doesnt help against double attack+critical strike of that red douchebag.
