Character Overview


Crystal is the second character in the game and one of the two unlocked by default. She has a normal starting loadout with the Revolver. Her B-Skin is unlocked by reaching 4-? (Cursed Crystal Caves) which is done by exiting 3-3 with any cursed weapon found by running a crown.

Preloop Strategy Guide


As Fish and Crystal are both characters unlocked by default, they both make for great starter characters to learn the game with. In Crystal's case hers is all around extra defense, which is useful while learning to avoid taking damage.

Active Rating: (Text)
Crystal's active may seem like a mixed power as she is forced to stay stationary and cannot fire her weapon, however this is still a really useful ability as she can choose at any time to undo the shield. Correct shield usage is all about timing - Crystal can time her shield to deflect enemy bullets, then let go of her shield once the projectiles are dealt with and continue on. If an enemy ever fires in close quarters Crystal can panic shield, or she can use it in opportunities to get easy damage back if an enemy telegraphs their attack well such as Snipers.

Passive Rating: (Text)
Having 2 extra HP is a nice little boost as Crystal can take some more damage before getting killed. There is still plenty of use taking Rhino Skin at this stage of the game, as having 14 HP gives her a lot of breathing room for mistakes, something that is seldom given to other characters. In this situation having healing mutations is particularly recommended, as playing without any of Bloodlust/Rabbit Paw/Second Stomach will mean that Crystal will struggle to climb back up to full health given sparse preloop drops.

Thronebutt Rating: (Text)
Crystal's Thronebutt is a bit gimmicky, but is pretty useful at this point of the game. She will sacrifice a bit of her shield time in order to teleport anywhere on-screen, which could put her out of danger or directly into it. This is a mutation that requires constant concentration in order to utilize properly, this mutation can be skipped if that does not sound appealing.

Crystal's preloop guide is fairly short as she basically just gives better defense during the run. Some practice should be put into shielding efficiently, otherwise gameplay will be very vanilla.


Loop Strategy Guide


Crystal is given the choice between two ultras upon entering loop, which easily propels her from being a good character into one of the best ones.

Fortress Rating: (Text)
Fortress is easily one of the best ultras in the game as Crystal reaches 16 max HP, which is a significant advantage over any other character who only has 12 HP max. While she is not fully invulnerable and will still die to sources such as Vans or Laser Crystal contact in one hit, many other common sources of damage she can shake off. Another perk is that she doesn't need to take Rhino Skin and can use that mutation slot for something else (unless if Rhino Skin is the best option, 20 HP is very good). Any healing mutation is strongly suggested at this point, especially if running Strong Spirit as trying to heal back up to 16 HP to recharge Spirit may still be difficult.

If running Fortress then that means Crystal will just have her default shield, this is still a fairly useful tool in loop but should be used carefully. This is most useful during boss fights such as Throne and Throne II, it's more of a risky decision to use when surrounded by dozens of enemies unless if she has a melee weapon ready to swing the moment shield is up.

Juggernaut: (Text)
Juggernaut is often overlooked due to how powerful Fortress is, however this is still a good option in loop. The main downside of a stationary shield is that if it's mistimed an enemy projectile could hit Crystal just as the shield wears out, however in Juggernaut's case Crystal will already be on the move making this unlikely. It also lets her push towards some enemies to close the gap, such as Big Bandits or Elite Grunts. Less specific advice applies to this ultra as it's basically up to player's judgement on how to best use Juggernaut, it provides a lot of flexibility.

Thronebutt Rating: (Text)
Due to the volume of enemies, Crystal's TB is best used in order to retreat from situations rather than throw her into the middle of the fray, although it could still support aggressive playstyles for an otherwise defensive character. This is a niche mutation that may be useful only to specific players, while others may opt to use the mutation slot on something they find more useful instead.

The crux of Crystal's benefits is just that she has better defense, which lets her respond to situations better. This makes her advice less specific than other character guides, but still should be overstated that she is a very great character at this point of the game.


Meta Strategy Guide


Note that this is an advanced guide, it is meant to be used by those primarily looking at loops 3+. This builds off of content shared in the meta guide.

Crystal holds the global world record and is widely considered to be the best character in the game. She is undoubtedly a great character at any point of the game, and is extremely useful for anyone learning meta or wanting to push their personal best as far as possible.

Fortress Rating: (Text)
Fortress is widely considered to be one of the best ultras in the game, if not the best. Having 16 max HP means that Crystal is able to shrug off damage in far more situations than other characters and makes deeploop far more forgiving/easier. This is especially true during boss fights which are the biggest skill checks in the game, that extra HP can often make all the difference.

Another reason on why Fortress is so good is because it makes Rhino Skin an optional mutation, which gives the choice of taking either another very good mutation or leaning into 20 HP.

Crystal's P7 Choose 2 From:

Characters typically take eight 'necessary' mutations and then give the 9th spot to either a healing mutation or Back Muscle. In Crystal's case, she gets to take two of these instead. Be aware that this is NOT advice for getting WR, just advice on Crystal's deeploop gameplay in general;

Many combinations have been run even in very later loops, the winning combination seems to be Bloodlust + Back Muscle, although other options like 20 HP or Paw + Stomach ('Pawmach') have their strengths as well.

Crystal's shield can still get some usage in deeploop.
First is Throne II, who has a laser attack that shoots out more laser orbs and have them last longer with every passing loop. Crystal can shield during this to stall as long as possible which helps conserve rads.
This also has some use during Big Bandits fights, such as if some Bandits have Crystal in their line of sight and are firing while the others are trying to charge to close in. Shield is a good way to stall until the charging ones are close enough.
One other particularly useful point is the Throne's fight. It can lose track of Crystal's position if she is shielding, so she can stand directly in front of the Throne (with some distance) and wait for it to walk forward (when it cycles between attacks). The moment it starts to walk she can unshield and shoot SPC at a diagonal angle to make the Throne walk directly into it, which will cause it to take most/all SPC damage. This is a more risky strategy, so practicing on NTT with debug is suggested.

Juggernaut Rating: (Text)
Because Fortress is one of the best ultras in the game, Juggernaut simply cannot hold up in comparison. It still can have a few moments to shine in deeploop, but the winner is clear here.

Thronebutt Rating: (Text)
This is a niche mutation that does not have a spot in meta at all given Crystal's potential, making this a waste of a mutation slot.

Crystal basically just makes the game easier due to extra HP without heavy strategizing needed, and her shield gives more breathing room at some important moments. This basically just makes the game more forgiving and gives far more flexibility in set building; sometimes the best characters are the simplest ones.
