Ferrix hasn't posted, but I want to keep things moving with at least one post per week-day for myself, so we'll forge on assuming he'll keep peppering away with his bow.
Girble deftly slips a stone into his sling and whirls it over his head, popping out from cover just long enough to let it fly. The bullet whistles through the air, but flies wide of the mark.
[sblock]Attack roll 4+10 - 2 (range) = 12 vs. AC 20[/sblock]
Erethinol extends her wand muttering under her breath and shaking it, but without results this time.
[sblock]UMD roll 7+11=18 vs. DC 20[/sblock]
Donnybrook smoothly draws and fires his bow in two quick motions. The first arrow grazes the sentry's cheek while the second skewers him in the abdomen. He roars in pain, badly wounded.
[sblock]Attack Rolls: 8+14=22, hit!; 16+9=25, hit!; Damage rolls 4+2=6, 6+2=8, 14 total. This Bugbear has now taken a total of 25 HP. Remember to declare if you want to use Rapid Shot or Manyshot. You specified two arrows this time so I assume not.[/sblock]
Slight correction for Lucas. The Arcane Eye can be created anywhere within your current line of sight, so I'll make the assumption you created it near the cave entrance instead of in front of you. Spoiler below for Lord Raven, so he can announce what he sees in character.
[sblock]Lucas is disoriented for an instant as his perspective is split between his own location and the cave mouth. Quickly getting his bearings he looks around and ses that there are indeed two bugbears at the cave mouth. In addition, there's a goblin who seems to have been lounging on the ground, but both he and the other bugbear are now moving toward the ledge. He also notices that the cave goes back at least 60 feet (the limit of his darkvision).[/sblock]
Sirius sends more arrows arcing toward the bugbear, but without luck this time.
[sblock]Rolls 1 (auto-miss) and 7+6=13[/sblock]
The bugbear is joined by his comrade and they both take a shot at Donnybrook. Fortunately their arrows skitter and shatter against the rocks, missing him by a wide margin.
Another spoiler for Lord Raven:
[sblock]The goblin rises to his feet but doesn't move toward the edge of the slope yet. Instead he makes some familiar passes with his hands. Even without being able to hear the incantation, Lucas easily identifies the elementary spell being cast: Mage Armor.[/sblock]
Ready for new actions.
