The bridge is rough terrain, so using both your movement and action, and you get about 2/3s across the bridge.

IrRy0's turn.

((Ahh apologies, I thought it was Orc 1's turn!))

Zacharias' eyes roll back and he begins to chant, his voice is deep and melodic, though there are words they are in no particular language.  Grabbing his amulet from around his neck he holds it out in front of him.  Tongues of flame start to form around his hand clasping the amulet, these then coalesce to form a fiery bolt, which he hurls towards the nearest orc.

Casting Fire Bolt: Attack: 8 Damage: Unable to parse dice roll.

As the bolt is unleashed the chanting stops.  Zach gasps for air as though he had just resurfaced from being underwater.  His eyes wide and arm remaining outstretched, he watches the bolt go towards its intended target.

((not sure why it was unable to parse, do not believe it hits either way - 2))

The closest orc, (orc 1) is asleep, roll your attack with advantage.

Advantage on Attack roll (2nd Dice): 22

The blast of fire hits the sleeping orc. The orc wakes up to the flames though. 

Mehmen -- Spoones -- Orc 1 -- IrRy0  -- Sparkrotfang (their turn) -- pocketmouse -- Orc 2

like I said earlier, using my turn to cross the bridge, dashing if i have to.

Make a acrobatics check to walk on the dangerous rope bridge.

4 acrobatic roll

You steadily scale the bridge. The bridge is rough terrain, so you make it about 2/3rds of the way across with Lurrinthis.

Mehmen -- Spoones -- Orc 1 -- irRy0 -- Sparkrotfang -- pocketmuose (their turn) -- Orc 2 

I'm pretty sure Elinar's still hidden, but just in case he's not, bonus action to hide: 24, and then he'll shoot an arrow from his location. Shortbow attack: 21 Damage: 10 (includes sneak attack)

After shooting he'll use his movement to begin to cross the bridge.

Make an acrobatics check.

Acrobatics: 19

The bow shot hits orc 2, and in retaliation, orc 2 rushes to one of the bridges rope holds and brings his axe down in it.

Attack: 17 Damage: 10

The rope begins to snap. But doesn't break.

Mehmen (their turn) -- Spoones -- Orc 1 -- IrRy0 -- Sparkrotfang -- pocketmouse -- Orc 2

 (ooc: someone stop that orc!)

Richter glares at the goliath for waking up the Orc, but chose to hold his tongue. At least for now anyhow, but somebody was definitely getting a mouthful later. Probably. Maybe. Until then, he pulled out the one card he kept tucked up a sleeve and says, "I was hoping to save you for a rainy day, but I guess now is as good as any time." He then throws it, whereby it combusts into a blue flames that seek out to envelop Elinar, Lurranthis, and Geist.

The flames however do not burn, but rather give off a feeling of urgency and request of trust. Those that trust disappear as the flames snuff out on the spot, only to reappear depositing their would be victims. Presumably being, right behind the Orcs, if not but a few feet away from them. One flame lingers as a smaller orb by geist, whispering advice and words of encouragement.

Action: Imbue Elinar, Lurranthis, and Geist with the Runaway Tale. All three may use the same reaction immediately to teleport up to 30ft.

Runaway. You tell the tale of an adventurer that could escape an confinement. The target can immediately use its reaction to teleport up to 30 feet to an unoccupied space it can see. When the target teleports, it can choose a number of creatures it can see within 30 feet of it up to your Charisma modifier (minimum of 1) to immediately use the same reaction.

Bonus Action: Cast Guidance on Geist.

(Technically speaking, Elinar gets to choose, but I cannot imagine he wouldn't take those in danger of falling if the bridge collapses with him given the choice. :P)

(There. Now you guys can stop the Orc. Your welcome. :D)

(To clarify: Elinar can choose to take someone with him to generally the same space as where he ends up, or can he choose to plop one of the orcs anywhere, such as over the chasm or at the bottom of the chasm, if it's within 30 feet?)

(Its not quite that broken. After you teleport, you can basically pass on the same ability to teleport onto 3 other creatures. Who can then immediately teleport up to 30ft into an unoccupied space of their choice.)

(Don't think you wanna give the bad guys the choice to freely teleport away from you guys, and maybe run off to call in allies...)
