New achievement thread! *SUGGESTIONS!*

These are my suggestions for new achievements! Comment and tell me what you think, or if you would change anything. I just think that if new achievements were implemented, it might give those knights who have completed everything already some new content or goals to achieve!
Add your suggestions for achievements here! I will add my favorites to the OP (with credit of course)

hmm and what are your reasons? i figured someone might be against it, but i think that putting achievements only for PvE is biased and wouldn't direct new players to try out ALL of the content that the game has to offer. i notice you didn't include "no BN achievements" however both are in the coliseum tab.

I didn't include BN because I didn't notice it and as for the PvP achievements, they can be achieved immorally(getting your guild to help you get a "million kills" achievement.etc).

I wouldn't call the sprite ones "animal lover" etc. How bout different forms of "trainer" instead? Sprites are not animals after all - lore specifically states as much. It would also allude to pokemon, sorta.
How bout kill counts? One for each kind of monster- lower tiers have different cheevo names. I'd say defeat 100 of each kind of monster in each tier, except the rares - like love puppy (you mentioned Heartless), soul jelly, etc. Dapper Doom! haha. Lot of cheevos there. IDK if I'd become extremely depressed if they had a monsterkillcounter on your profile somewhere, like...I've vanquished THAT many slags? Really? Oh lord.
PvP cheevos are fine. Cheevos indicate you did something and shouldn't be excluded unless the method of achieving said thing is removed *cough minerals cough*. There's ways to "abuse" most things, pvp or pve.
Some weird ones:
"Nuking isn't the solution": Hit the Gremlin Incinerator with a Bomb Shell in the last fight of Compound 42.
"Zap Camera": witness quicksilvers do the dirty work for you 100 times (allow quicksilver monsters to kill other monsters, you have to be within 20 tiles for the count to occur).
"Camel": carry a water orb for far longer than necessary (counts the tiles traveled, not the time your knight holds the orb, does not count tiles already stepped on so you can't just walk in a circle). Easily achieved during Shroud of the Apocrea.
"I love lamp": smash 500 lamps. Alludes to Anchorman.
"Zydration": smash 500 tombstones. Tombstones in shroud of the apocrea do not count. Alludes to Repo! The Genetic Opera.
Lots of smashable cheevos could be made.
"Listener": talk to 100 "different" misc NPCs. Important NPCs don't count.
I would make things have alliteration and allude to things whenever possible (though staff would probably have to be fans of said alluded-to things).

@Dahall: hmm, perhaps could add a restriction to make the lockdown and blast network achievements only applicable with random lockdown and random free-for-all. i see that being a big problem for blast network, since match sizes only require 4 people minimum, while lockdown requires at least 8 and there isa no guarantee that you will get in with only friends. Also one thing about achievements: you don't gain any sort of prize for completing them, so while it may be possible to cheat-to-achieve them, the real players will understand that they earned their achievements.
@Dracora-Speaking: thank you for your input! i will work on new names for the sprite achievements. kill counts would be a very cool thing! the question is though, how would you classify the higher achievements? would it be by killing the same amount of different tiered enemies of one family? or perhaps killing any tier of one family more times to get better achievements? OR a mix of the two; killing more monsters per achievement while going up in tiers? will think about the best combination, suggestions would help :). as for your other suggestions, i loved the idea of implementing danger mission or prestige achievements, will think of some new ones for those. my favorite achievements are the "Dapper Doom!" and "Listener," i will add them to the OP.

Any achievement which is tangible is exploitable. There's no sure-fire way of preventing that.
With that in mind, there's only two true choices: accept they may be exploited and have limited value, or don't have tangible achievements.
Anyhow, I don't think people would care enough. If you want to claim you're good in Lockdown or BN, you might to show it. Not just have one achievement that says "I've played it for a long time".

@Bullpig:
- Champion: Complete all missions on Normal difficulty.
Sounds okay.
- Hero: Complete all missions on Advanced difficulty. (Unlocks Champion achievement upon completion, if not already achieved)

- Paladin: Complete all missions on Elite difficulty. (Unlocks Champion and Hero achievements upon completion, if not already achieved)

Would be cool if we could actually converse with non-important npc, though the game doesn't provide enough miscellaneous npc interaction in haven or in clockworks. Wish that could change a little. Like being able to talk to the patrolling guard or something like that.
- Courageous: Complete every Danger Mission on Elite difficulty.
Sounds good, and would also be cool if you put a number cap on normal danger mission encounters in the clockworks.

sounds good.

sounds good, though hunter would not be bad either.
- Completionist: Collect every item in the game. (Usables, Costumes, Rarities, Accessories, and Recipes do not count)
Completely agree and want this. So from armors/helms, weapons, and shields. This should not include any weapons that has to be obtained though a box like the Red Saber or items that has to be obtained though a downloadable content like the Warmaster Rocket Hammer. Also, this achievement should be a temporary achievement sense the game constantly keeps adding new gear. Though the game will record any times you have hit the achievement and label a time for when you achieved it. This way, when a player inspects you, you will see they have achieved it in the past, but if tat player do not have all gear currently, the achievement badge will have a dimmed glow showing that they do not currently have all the achievements. I feel this is a much seeked after achievement and it should be modified in this way.
- Gladiator: Collect every Sword in the game.
Sounds cool, or master swordsman.
- Marksman: Collect every Gun in the game.
Sounds good, or gunslinger.
- Bombardier: Collect every Bomb in the game.
Sounds good, or fuse head.
- Thick Skin: Collect every Armor in the game.
Sounds good, or metal skin.
- Headstrong: Collect every Helmet in the game.
Sounds good, or hammer head.
- Guardian: Collect every Shield in the game.
Sounds good, or impregnable.
- Superstitious: Collect every Trinket in the game.
Lol, that sounds good.
- Hoarder: Collect every Material in the game.
Lol, sounds good, or pack rat.
- Explorer: Collect every Artifact in the game.
I like it, sounds good.

Sounds good. Though why not make an advance achievement that is over paladin that requires the player to beat some hard missions solo on elite difficulty like vanaduke, weight of darkness, ect..
— hmm, like a "Lone Wolf" achievement. I like the sound of that. Except that sounds a little too easy, so how about solo every mission on Elite difficulty (Including bosses).
Sounds good. Though removing your, and just cold as ice or Frozen Kingdom or i'm not sure.
— I only said "You're as Cold as Ice" because it refferes to the song Cold as Ice by Foreigner and the chorus says the whole thing but I suppose since the title of the song is simply "Cold as Ice" that would also work :P
I also listened to a few of your suggestions and edited a few achievements. Thanks for your input!

"Broken Sparks" - Loose your emergency revive within first 5 minutes of any mission
"Fleeing death" - Die within first 5 minutes of Reviving.
"Seraphtastic" - Reach level 50 on your Seraphynx
"Maskerrific" - Reach level 50 on your Maskeraith
"Drakorrection" - Reach level 50 on your Drakon
(My puns suck...)
"Live life" - Complete a entire arcade mode from Haven to Core
"Dumb Ways to Spark" - Spark three times in one mission.
"Natures Equality" - Collect all Nature Sprites in Fire Storm Citadel's second stage.
Thats all I got...

"Live life" - Complete a entire arcade mode from Haven to Core
This already exists, it's called "Cradle and All".
And I'm against the "complete all missions on X difficulty", simply because we can't go back and do the starter missions on elite. Unless this only counts missions once you reach haven, in which case, sure! ... Just make sure it doesn't include talking missions that you can't choose the difficulty on.

"Broken Sparks" - Loose your emergency revive within first 5 minutes of any mission
— I like the idea, but at the same time it seems like an achievement for doing nothing
"Fleeing death" - Die within first 5 minutes of Reviving.
— Same with this one. Seems like being rewarded for nothing. Maybe a shorter time period would make them better.
"Seraphtastic" - Reach level 50 on your Seraphynx
"Maskerrific" - Reach level 50 on your Maskeraith
"Drakorrection" - Reach level 50 on your Drakon
— These seem a bit repetitive, but still good.
"Live life" - Complete a entire arcade mode from Haven to Core
— This already exists.
"Dumb Ways to Spark" - Spark three times in one mission.
— Not bad, but easy to achieve.
"Natures Equality" - Collect all Nature Sprites in Fire Storm Citadel's second stage.
— I really like this one :) Possibly a different name though

== It was just a "silly" achievement idea, sillyness is fun. :P

How about...
"Unafraid of the dark": Clear the unknown passage without dying. (Includes 10-1 "It came from below" not just shadow lairs)
"Magician": Collect every elemental item in the game.
"Hate light": Collect every shadow item in the game
"Suggest name!": Collect every piercing item in the game
Also for completing achievements, you should get rewards, like in super smash bros., Why try and get them when you get nothing? Prizes could include crowns, prestige, and rarities. The difficulty of the achievement will determine what kind of prizes you'll recieve.

Dead Weight - Die 10 times on a single floor.
Heartless mk2 - go through an entire level without picking up a heart.
Found you! - reveal 10 invisible enemies using hewing haze.
Full of Love - mark 10 enemies at once using the heart attack.
It burns! - light 10 enemies on fire using the firestorm attack.
We need backup! - find and use 5 recon flares.
Tank - lose 200% of health on a single floor without dying.
Popular - have 25 unique knights inspect you
Old School - be from the beta
Old school mk2 - have a legacy achievement

I Am Gilgamesh!
-Have collected every Sword weapon in the game (includes weapons that have been in inventory at any period of time, so just having the data logged counts) (reference to Final Fantasy's Gilgamesh, who is lots of things, but mainly a collector of legendary weapons)
Bullet Hell
-Have collected every Handgun weapon in the game (see above) (reference to Bullet Hell type video games, involving lots of bullets...so lots of...guns...)
Bomberman
-Have collected every Bomb weapon in the game (see above) (literally Bomberman)
Can't Shoot Up!
Defeat an enemy with a Grim, Wild, Stoic, or Primal Buster. (reference to MegaMan and his MegaBuster, who could never shoot in the up direction. RIP).

Ultimate explorer - travel on every single type of level in the crade (including events, expansion and so on)
Bullpig said "Smooth Talker: Bride King Krogmo."
ahahahahahahahahahahahahahahaahaha.
Also, no LD achievements.
