(well, you have an advantage. they have to run to get you. Plus, here's something.) Balzavur, a paper airplane come down and lands in your hands. Reading it, it says "Until Army comes out, Water is cleaner than usual. It is not difficult terrain until the Army comes out."
Atom moves quietly through the trees to I6, He then proceeds to motion his orb around him, after a full rotation he thrusts it forward a little bit then yells out "Let poison fall from my hand!". Casting Poison Spray Attack: 17 Damage: 10 (Poison Damage)(Spell Save DC: 13)
Okay, well in that case, Balzavur closes the gap with Atom and uses the energy of the Shadowfell to curse him. He then stows his shield and attacks with both hands on his longsword, aiming for the snowy throat of his foe.
Longsword attack: Attack: 21 Damage: 9
[OoC]: I also critical hit on a 19, so I'll roll the extra damage just in case: 10
Additionally, if I kill him, I gain 4HP back.
If the blow kills his enemy, Balzavur will sprint the remaining distance to the trees and take full cover in whichever square on row K that he can reach.
Damián sees the dragonborn hit with poisonous gas and his eyes go wide. This is serious business and he had not truly considered the consequences. He rushes to C5 and fires off an eldritch blast at Atom from behind half-cover.
Attack: 8 Damage: 9
Then he backs up again to take full cover behind the tree at B3 The sound of the bullywug army approaching fills Damián with dread.
Balzavur takes his shield which for some reason he wasn’t wearing, and straps it to his back as he swings at the opposing halfling. It connects, and Atom hangs on by a thread. He moves away, and risks Atom attacking (I’ll put you at K4)
Round 2 in the swamp.
Damian mistakes to sound of pitted patter for Balzavur falling, and shoots at Atom also. He is still wide by a mile, and moves once more.
[OOC: I did roll the hit wrong, I was looking at the wrong skill so I thought I was close enough >.> and as far as damage, D&D Beyond lists my modifier which I thought attached to my damage, that's my mistake. Since Balz is hiding within trees, is it a disadvantage on attack rolls? I also apologize, I'm at work, I'll post when I can.]
(No, he just moved there. It’s your turn to do thins, and you can really target Balz anymore since he has total cover from being behind a tree unless you go to a tree too. You also get an attack of opportunity.)
