During hiatus I'm revisiting the WWtH monsters and trying them out in actual 4e combat encounters. So far I've done a beelion test and a doppelganger freak test. I ran the sample encounter for the laughing lambchop lizard last week (this post is late because I've been dreading how much rework the monster was going to need). The party is still:
A goliath warden
A gnome bard
A longtooth shifter ranger
A deva invoker
The sample encounter for the laughing lambchop lizard is 4 regular lizards and 2 lizards of lightning. Again, the map was Dwarven Outpost from the Miniatures Game Starter Set. This time the monsters were inside the ruined outpost building and the PCs were coming across the bridge toward it. The party heard the lizards and the ranger managed to sneak up and get a look at them without alerting them.
The ranger used her surprise round to fire arrows at the lizards, but then the lizards won initiative and swarmed her. Before I even rolled the first attack I realized that letting each of the six lizards catch her with a lethal shock would result in instant nasty electrical death. So the first change to the lizards, before they rolled their first attack, was to remove the lethal shock power from the plain laughing lambchop lizards. As a result, most of the lizards didn't attack this round, but moved into better positions. The party moved closer and got in a few hits.
In round 2, one lizard of lightning had the ranger and warden in range for a lethal shock, while the other moved into position to catch the entire party. I quickly realized that adding an attack bonus and damage for each lizard in the burst would spell instant TPK, so lethal shock was toned back to only add bonuses for other lizards of lightning in the burst. Even with that nerf, since the ranger was hit by two bursts she was going to die instantly, so the 2d8 damage per lizard was nerfed to 1d8. The ranger went down anyway, but at least wasn't instantly dead.
With lethal shock nerfed and spent, the rest of the fight was pretty dull, mostly because I forgot to use the cheshire fade power so my lizards never pulled back when damaged like they were supposed to. I think I'll make that one "when bloodied" so there's no question of when to use it. I'm also changing the plain lizards from lurkers to soldiers since they no longer have a big boom attack and their job will be to shield the artillery lightning lizards.
