I don't see how you'd attack at disadvantage its magic not like it's a heavy bow or something you aim that takes much effort ether way you'd hit the guard though etc... (the guards however are wearing leather armor and have no shields)
Vitha maul will Land into the Guards head crushing his skull they falls down dead
Bernal Lands his spell on the guard he slows them down they are wounded
Hesken slashes into the the guards chest they flinch
Hammerstone is behind them all so he will attack at disadvantage and 1 of you at random rolling a d4
Hammerstone slames his Hammer towards To hit 9 also To hit: 11 Damage: 6
Hesken brings the blade of his greataxe up and, staring right at the guard who attacked him, licks a bit of the blood off the greataxe. He gives the guard an almost manic smile as a red froth begins to form and drip from his mouth. (Bonus Action: Rage) In his rage, Hesken will attack the guard that damaged his leg. (Attack: 13Damage: 15)
Feeling her pain subsides, Lassnera flares to show these these fools. Divine energy glows from her hand grasping the sign of the sun on her necklace and down to the other hand where she slings a Guiding Bolt towards Hammerstone.
