Round 1:

Koplony rushes ahead toward cover.

Kulum prepares to defend himself.

Swigg disappears in a blur of speed.

(Dorkas)

(Updated above) 

Move to 14 h

and cast green flame blade 

Round 1:

Dorkas moves up and readies a spell (I presume, but I'm getting the impression you may not understand how Green Flame Blade works...)

(Round 2: Koplony, Kulum)

(Updated above)

Kulum moves to H8 and continues to wait for an attacker to approach.

Swigg appears at H4 with guitar in hand and shouts out to Kulum. "Lets give this audience a show worth remembering. I suggest you join my team until we take down Koplony." (Wis Save DC 14)

Then he will duck back down behind the ice spikes Le Poof! 15

Round 2:

Koplony disappears without a sound.

Kulum holds his weapon ready (imagining his opponents might attempt to fight him.)

Swigg suggests a course of action Kulum can not take. (DC 14 Wis save)

(Dorkas is up. Kulum DC 14 Wis save)

Wis Save: 7

(sigh...why not?  The action isnt harmful to himself. Its just a bad tactic. The spell even cites several examples of obvious harm as doing damage. Im not asking Kulum to do damage to himself by any means. I spent a spell slot, Im using concentration, he failed the save FFS. What is up with this? With this spell I want to take him out of the game or have him join my team. Can I do that? I should be able to if he isnt hurting himself.  THESE ARE MY OTHER SUGGESTIONS: Pick one that works for you.

Dig a hole with his weapon and stick his head in the ground

Put a bandanna over your eyes and cover your ears and keep spinning.

Sit down and throw your weapons far away from you.

Get buck naked and dance like no one is watching

NONE OF THESE are as fun  as Kulum joining my team because they remove his agency and I would hate to play that game but they should work considering the wording of the spell)

This is the spell Suggestion - 

You suggest a course of activity (limited to a sentence or two) and magically influence a creature you can see within range that can hear and understand you. Creatures that can't be charmed are immune to this effect. The suggestion must be worded in such a manner as to make the course of action sound reasonable. Asking the creature to stab itself, throw itself onto a spear, immolate itself, or do some other obviously harmful act ends the spell.

The target must make a Wisdom saving throw. On a failed save, it pursues the course of action you described to the best of its ability. The suggested course of action can continue for the entire duration. If the suggested activity can be completed in a shorter time, the spell ends when the subject finishes what it was asked to do.

You can also specify conditions that will trigger a special activity during the duration. For example, you might suggest that a knight give her warhorse to the first beggar she meets. If the condition isn't met before the spell expires, the activity isn't performed.

If you or any of your companions damage the target, the spell ends.

(Kulum doesn't get to choose his team. That is determined by the dice mysterious unseen forces. He can certainly behave as though he is on your team.)

(Edit: As for what's fun, "Save or lose" isn't it.)

Im confused. Whats happening with my spell? This also isnt a save or lose situation. It may feel that way because I play to win. It feels like that is being held against me. I use my spells viciously and creatively. He aint killing himself he should do what I say. It seems like you are trying to tip the scales because my choice was too effective. He failed the save because I chose a target with a weak wisdom defense. If they both had strong Wis I would have done something else. Im...a little frustrated because im not going against the will of the spell. Im going against the will of a dm that doesn't like how I use my magic. That is lame.

 Give me mine!

(guess I'll take another one)

(Hey everyone so it looks like Suggesiton is a little too vague of a spell to be used in the arena. I was wondering if the participants of this match would be fine with me switching out suggestion for hold person and have the results be the same. My intention was basically to do a fun mind bendy hold person anyway.)

Round 2:

Dorkas climbs up and sttps out into the ice.

(Koplony and Kulum are up.)

(Sometimes I try and resolve vague or difficult problems in the arena by giving vague rulings. Sometimes the problems just go away before they ever actually get addressed. In this case I'm leaving the results up to you to interpret as you see fit, and if the problem comes to a point that a ruling is truly needed I'll give you something more clear. I was about to write "Kulum is petrified with indecision as he's locked in a state of confusion." Instead I wrote this paragraph.)

(Updated above)

 Wis Save: 16

Round 3:

Koplony moves invisibly and silently. He strikes, hitting Dorkas with a bolt of fire which streaks from J-12.

Quote from Brian_Avery >>

Koplony will cast Fire Bolt at Dorkas.

Attack: 18 Damage: 16 

...

Kulum is paralyzed in a moment of indecisive confusion before he clears his head to continue. (Apparently we're trading this for Hold Person)

(Swigg, Dorkas)

 Targeting Koplony from O7, Swigg casts Dissonant Whispers 8 (wis save DC 14)

Then he will Le Poof! 18

(Dissonant Whispers only requires that my target can hear me.)

(Total cover from Dissonant whispers means covering your ears, putting yourself in a box or some other situation where sound cannot reach you. Total cover is about my ability to hit you...and you dont have total cover from sound. Also, just because you are invisible doesnt mean I shouldn't know your exact location unless you hide. Its like a predator cloak, the air is distorted unless you apply the skill of stealth, but wutevs. ) 

This is where my opinion on the ruling comes from
