NPCs & Enemies Acid Rain - Hardmode Rain Event

SzGamer227

Spazmatism
For my 80th suggestion thread, this is my take on the idea of a Hardmode version of the Rain event.


The Basics

For starters, this event occurs the same way the Rain event does, except it is half as common, so it occurs much less frequently. The event starts and ends at a random time, just like it's early-game counterpart, but it would tend to last a bit longer to make up for being rare.

One unique hazard of the Acid Rain event would be that it turns all pools of water on the surface into pools of acid, which deals a small amount of damage and inflicts the Acid Debuff for 7 seconds, like a weaker version of lava. What is the Acid Debuff? Let me answer that for you, but I have to get through the basics first.

Also, just for the heck of it, anything that is on the surface that isn't immune to the Acid Debuff has a 10% chance every second to be inflicted with the Acid Debuff for 1 second. This can be avoided by being in front of background walls, holding an Umbrella, or visibly wearing an Umbrella Hat.

This may be trolling too much, but it would definitely be minimally annoying more than anything else. It's there for effect, even if it does cause trace amounts of damage in order to experience it. That'ts pretty much it, really, just a slightly painful visual effect.


Acid Debuff

The Acid Debuff would be a middle ground between Ichor and Cursed Flames Debuffs, which means (using the the existing mechanics) it would deal 2 damage per second and reduce defense by 10. However, I don't like either of those effects for one reason or another. If my proposed Change to Ichor and Changes for DoT Debuffs were added into the game, it would increase damage taken by 5%, do 5 DPS to enemies, and do 3 DPS to players.

Enemies that would be immune to the Acid Debuff would be the Toxic Sludge and all Acid Rain event enemies. As for players, we can add Acid Debuff Resistance to the Bezoar and its upgrades.

On a miscellaneous note, we could give Spazmatism the ability to shoot Acid instead of Cursed Flames so that there isn't a weird confliction on Crimson worlds. That is, unless we get a new Mechanical Boss which inflicts Ichor, but that's not very likely, is it?

I don't know how to incorporate that into an event.

I have a thread for traps, but I haven't ported it over from TO yet.
 
Sounds great, and the chances of it occurring are just rare enough for it not to get extremely annoying. Support.
 
Wherever the Mechanical Bosses come from. That place cannot be eco-friendly.
My theory is that the mechanical bosses were created by the cyborg to counter the three earlier bosses they represent. Of course, like all giant machines, they went rouge.

Anyway - I really like this concept. The regular rain event is just plain annoying and if this were to have a chance to pop up it would really be a cool addition.
 
Great idea!
And I very much like Caustic Trirant sprite... But one thing bothers me. He will have troubles with terraria landscape. I mean, he is good only on flat terrain, otherwise his legs would be hanging out...
