I note that D20Dazza is in Australia. So since Ery is going late in the round I'll do everybody's actions up to that point, then wait for D20Dazza's post. I've attached a picture of the creature attacking Lucas. I'm sure you'll all recognize it.
Sirius pushes one of the spiders from him and brings his axe down on its head in a mighty, whistling arc. Black ichor flies in all directions as the creature gives a spasmodic twitch and falls onto its companion. Siezing the opportunity, Sirius quickly swings again at the other spider, hewing off one of its legs. He checks his swing, brings the axe back again and connects with the thing's meaty body. It is dripping vital fluids onto the forest floor, but still barely moving.
[sblock]The dice like Ferrix so far: First attack roll: 20! A 7(+15) confirms for triple damage. Rolls: 10,10,5 + 21 = 46 points of damage! Cleave attack on other spider: Roll 15+15 hits. Damage roll 5+7=12. Second normal attack (on now injured spider: Roll of 6+10 hits (yes they're pretty easy). Damage of 2+7=9. One spider dead, the other has taken 21 damage and is barely alive.[/sblock]
Girble hears the sounds of furious battle and runs as fast as he can manage in his heavy armor to help. He draws his weapon as he goes, ready to dispatch one of the creatures when he's in range.
Please let me know which weapon Girble is drawing.
The horrible chitinous thing rushes the ensnared Lucas and sinks its black fangs into the wizard's leg. There is a searing pain as the creature's venom is pumped into Lucas' body.
Lucas takes 5 points of damage. Fortitude save DC 15 poison: Lucas rolls 12+4 and succeeds!
Donnybrook draws arrows and fires furiously at the thing attacking Lucas. All of his shots strike true and the creature emits another ear-splitting shriek, but it seems to be simply enraged by the attacks.
Just to clarify, it definitely took the damage, it's just not down yet

Donnybrook's attack rolls:
10+12=22 Hit, 4+2=6 Damage
2+12=14 Hit, 2+2=4 Damage
16+7=23 Hit, 4+2=6 Damage

Lucas knows now what they face. The abomination known as an Ettercap combines the worst traits of spider and human. Fortunately he also knows what to do with such a thing. He points his wand at it and intones "Dulak". 5 glowing points of magical energy launch themselves from the wand and home in unerringly on the Ettercap. They slam home, tearing great chunks of chitin and flesh from its body. The thing flies back to land in a smoldering heap on the forest floor.
[sblock]Knowledge(Dungeoneering) check 16+17=34. Feel free to look up the ettercap in the SRD.

Damage on the MM: 2+3+3+3+4 = 15. It drops

Waiting now for D20Dazza's post, when Ery and the remaining spider (if it survives) will go
