I would get farther away as a bonus action. Also yes, my firearm has been allowed

but you can't because A, you're in a 12x12 box that you can't escape from, and B. it's an arena with a 100 ft diameter, which means that you can't get farther than 100 ft from me

Due to math, I could fly to a height of 60 ft, and be within 120ft even if i was on the other side of the arena, which i'm not. A^2 + B^2= C^2 => 100^2+^60^2<120^2

The wind wall causes the attack to be with disadvantage, Asriel.  I am allowing firearms because they are in the rules as written, are not magic items, and he asked.  I think that's a good compromise.  Roll a second d20 and add your dexterity modifier, Asriel.  Also, your brutal critical and rage don't work with antimatter rifle.  Nothings stops him from leaving the box, however.  Read the spell's description.

Also... Doesn't windwall block it?

Yeah, small creatures cant, nvm, but projectiles can't...

Hmm, good point.  The first attack is blocked, Asriel.  You now know to do movement, and TELL ME WHAT IT IS.

ILT, your turn.

After windwall breaks down, I sic my mastiffs on him. 17 10 8 4 11 18 14 19 12 15 9 16 10 12 12 227 9 19

Tarrasques, u can only have 1 pet at a time...

Since when...?

Your turn...

Sorry for being so long guys.

So apparently, ILT sics a bunch of mastiffs at Asriel, and Asriel shoots him twice with a laser gun, hitting once. The fiends of Sedge are cheering loudly, and the arena starts to darken, casting dim light over the entire place.  At the end of ILT's turn, the pool of water erupts, and sprays psychic water throughout the arena.  Both of you make wisdom saving throws.  The DC is too high for the dogs and mules to make. Anyone who fails takes 10 psychic damage.  If you guys roll a 23 or higher, you take half damage.  Then it's Asriel's turn.

(In the future, discuss pets with me.  I said mundane items, not creatures, but I was gonna let the mule slide.)

After Asriel goes, pause for me.  I'm not gonna be here until tomorrow.

Not even gonna try: 12 radiant damage it is.
