It's been a while, but it should spawn an enemy called the "Cangoler" and you have a limited amount of time to beat it.

Another question: how does the 'challenge under the ice biome' work? I found the special "arena" in the underground ice biome, clicked the middle object, then died in a few seconds without explanation.

I've never tested this and calamity, so I don't know. Probably random.

i dont know if anybody asked this already

but in calamity, does the hell arena always spawn opposite the brimstone crag? or does it spawn in any side? does it break parts of the crag if it does spawn on it?

Bug Report – Snaker Mod (devilish arena)

During world generation, tModLoader throws an IndexOutOfRangeException:

SnakerGenSystem.SpawnCangoler(...) - SnakerGenSystem.cs:line 30
This happens with the latest tModLoader (1.4.4.9+2025.03.3.1).
Please check array bounds in your world generation code.
Thank you!

Mage weapon? DEVIL SNAKE STAFF!
Does the boss' giant fire ball attack.

It's in the Underworld, and there's a Devilish Riftmirror item for you to enter the subworld without finding it.

i cant find the arena and that is something that annoys me

Without any genuine context of what Rev does on my end, I tested it and it does a lot of damage but almost everything it does is very telegraphed, so I felt like it was reasonable to put in early hardmode. You don't need wings (though they obviously help) and the boss doesn't have insanely high health, so that's where it went for me.

I'm playing with the boss checklist mod and am doing a Revengance playthrough in Calamity. I was just curious, the boss checklist places the snake at the first boss you should fight in Hardmode, I assume thats probably just where it got put and not a real representation as the damage done is absolutely insane, a pebble falling on you is nearly 300 damage and while its not extremely difficult to dodge these things with some practice, it just seems odd, so just was wondering the mod authors opinion.

im using a super long list of QoL mods, but none of them are supposed to alter NPCs in any kind of way. though, i could send the full list anyway if you'd like me to

Weird, I couldn't replicate anything. What mods are you using?

no, it was a singleplayer world. and.. i guess the first part of the fight? as soon as i loaded in the snake was invisible

Are you in multiplayer? And what part of the fight?

uh.. the snake is invisible? not sure what could have caused this, but i cant really damage or reliably dodge it. any fixes?

The Devilish Riftmirror can get you there (50 Obsidian or 5 Snake Brick and 1 Soul of Night at an Anvil).

I used Fargo's Mutant mod insta bridge and cleared out the portal because I forgot I had the mod, is there still a way to get into the sub world?

I am not interested in a project that large I'm afraid. Plus, I've got *way too much* to get to first, by the time I finish what I'm doing right now chances are what I want to and can do is completely different. I have years of projects planned.

Unless you pay me. Then I'm open anytime.

ok but can you put it on a list so you can do it when your done with the stuff thats going on?

I do not have time for more projects, I've already got way too much going on. Sorry!

Please make a mod that allows you to transform into bosses :)
[wall of flesh,moonlord, might be to hard to do] I want it for my multiplayer minigame server!

Yes.

is this compatible with multiplayer?

Because it's a survival event. You're not meant to damage it.

Why cant i damage the thing under the snow

Nevermind it's through the game menu

How do you leave the arena?

day 35, I've entered the void, escape seems plausible now, all I see in front of me besides the eternal darkness are three words: "tiles loading: Complete". It's felt like days, I feel whatever has trapped me here is taunting me

Day 34, I am still stuck in the snake dimension, my rations are running low. I've been able to scavenge whatever edible meat I can find from the giant snake. I miss my friends, I miss my family. Will I never find a way out?

This is a commission, so no. I wouldn't need much help anyway, most of my mods are sufficiently skilled or personal projects, sorry.

is there any way i can help whit the mod, i make music. btw the sprites look really cool

Absolutely, that makes sense. Soon.

I found a bit of an issue with this mod during world gen. If the tower containing the portal generates under lava, the portal won't spawn, and thus the boss is inaccessible. Could you either allow the portal to spawn in liquids or, ideally, force the tower to generate above the lava?

Thank you, Gabe! :)

Fixed! Plus new content that's been on backlog for a while.

Devilish Arena seems to need an update to the latest tModLoader version as-of October 1st. Fatal error on load.

I'll add a craftable item specifically for QoL, but do note that if you have a portal, you can mine it with any pickaxe with more than 100 pickaxe power and place it wherever you feel like.

Would it be possible to add a craftable teleportation device to the subworld? For cases when the fixed underworld portal does not spawn or just QoL to avoid the trip everytime you want a rematch. Thx, also, really cool snake ^^

awesome, thanks for responding and fixing up multiplayer, we'll be sure to give it a shot, and the trailer looks great too

worms

Alright! Trailer and update are out, there should be near full multiplayer support on everything in the mod now! I know the event works (almost certainly) perfectly, though there may be some minor issues with other things.
Let me know!

Funny enough, the subworld *does* work, but the event itself doesn't. I'll work on that immediately! If all goes well, that'll be done by today or tomorrow.
and thank you!

does this mod work in multiplayer? me and a friend want to include this in a modpack, but we don't know if the subworld will work in multiplayer. the mod looks awesome regardless though.

Correct! I'd never take up such a large space in-world to house a relatively minor arena.

sorry if you've answered this question already, but this arena is a subworld, right? So there isn't a giant arena just sitting somewhere in the world?

The Art is amazing!! Well done on this.

W mod

Just tested it, and yes it is!

Does this work with The Depths?

That issue has to do with Dragon Ball Terraria, not my mod. I suspect they just don't anticipate such a small world since the arena is a ~300x300 subworld. Report that to them.
