Botzu's Quick Evaluation

+ Trait: Significantly reduced redeployment time
+ Reduce self deployment Cost by 1
+ Easy to max potential for even lower DP cost
+ The go-to human sacrifice when you need to delay enemies or soak big attacks or enemy specials
- Extremely low ATK means she can't do much other than take hits
- Skill effects quickly wear off and then she can't do much

Operator Overview

“Ahaha... You won't need to worry about any ambushes or assassination attempts. Because I'll aaalways be here with you.”

Gravel may seem flirty when you first pull her, but she’s actually just an honest person being upfront about her feelings. To support her beloved Doctor’s plans, this 4* Fast-Redeploy Specialist uses her strong Defensive abilities to stall the enemy’s advance and tank nasty enemy Skills.

Gravel has a quick Redeploy Time, and she is also incredibly cheap. Her base DP cost is low and her Talents – Fast Redeployment and Support of the Little – decrease it even further. She is meant to be dropped down multiple times in a battle to delay targets, soak damage, or trigger dangerous abilities, and her Skills support this stalling strategy: Shadow Assault gives her a huge DEF boost and Rat Swarm gives her a massive damage-soaking shield. Both Skills trigger on deployment and decay rapidly; once they wear off, call Gravel back so she can catch her breath and come back fresh when she is next needed.

In keeping with her Specialist classification, Gravel isn’t very good at anything outside her particular niche. Her DPS is atrocious, and she isn’t much of a tank once her Skills wear off. But if you’re having trouble with the blast of exploding spiders or the binding spell of Sarkaz Casters, Gravel is the woman for the job.

Newbie Tier List Explanation

No flashy extra utility here, she just takes hits and takes 'em like a champ, but a lot of times that's all you need your Fast-Redeploy to do. Her cheap DP cost lowers the cost of multiple redeploys. Even once you have the higher rarity Ops in this Archetype, she'll still be a better choice in some situations. Also, her E1 RIIC base skill is fantastic, so she should be promoted anyway.

Skill Discussion

Note: Gravel must be deployed for her Talent to take DEF buff to be applied.

You likely don't need me to tell you why Gravel is good given how ubiquitous she is in the early going. She is still the best at that bait niche well into the endgame, even sometimes appearing in high risk CC. Generally she works more than fine at E1 already, but given that she is a unit many people like to E2 anyway, her Masteries have some decent value with big gains, though they are a hefty overkill.

Module Analysis

Operator Impact: Low/ No

Meta Use: Medium

Explanation: Gravel's DP cost is already dirt cheap at 5 DP.  This means her DP cost with multiple deployments maxes out at 10 DP.  A normal retreat would refund 5 DP, where with the Module it would refund 8, for a net gain of 3 DP for each retreat (at the third and subsequent retreats).  Although this isn't nothing, it also isn't enough to matter in the vast majority of situations, especially if you consider that the first 2 retreats gain even less, and the only place where that extra DP will matter is early in the stage while you are still deploying your team.

On top of that, Gravel's kit is defensive, so the player is likely using her to delay enemy advancement or to damage soak at specific times.  This will typically mean fewer deployments and also that she is more likely to die.  Since no DP is refunded at all on death, this further reduces the Module's usefulness.

Base Skill Analysis

Gravel gains her second RIIC Skill at Elite 1.

Is it worth it?  Absolutely!  This is tied for the highest Factory buff, and Gravel is a good strategic Specialist that will end up being leveled and used anyway.

A girl no one would ever believe is a knight, were she not to divulge that fact.
Some of the things she says about the Doctor have raised questions about her mental state... Fortunately, no other issues have been reported.
Blushes easily when excited or emotional.

Gravel is a level-4 knight, barely mid-rank in the hierarchy.
But the title 'Knight of Kazimierz' is itself a status symbol. It is hard to imagine another knight with such status, other than Miss Nearl, who would stay with a little-known outfit like Rhodes Island.
Of course, Gravel is a special case, since her reasons for being here are obvious to everyone.

Increase Trust to 150.
With the passage of time, knighthood has evolved from a title of nobility to a profession. No longer do they maintain a stuffy, goody-two-shoes image.
Knights versed in covert ops such as Gravel are now fairly common.
But to rise to knighthood from such a humble background like Gravel's is still a rarity.
Indeed, she was sold to Kazimierz as 'chattel,'with a barcode on her shoulder an indelible reminder of her origins.
From those modest beginnings, she worked her way up the ladder to eventually become a level-4 knight, and just as she refuses to hide her barcode covered, has never hidden her past from her curious comrades.
While we don't speak of people as 'chattel' here at Rhodes Island, and knights don't have any special status over anyone else, her honesty and openness is still very much appreciated.

Increase Trust to 200.
Most Operators at Rhodes Island answer to their codenames as their new names. They leave their pasts behind, and some use those codenames as the first step intheirnew lives at Rhodes Island. Naturally, to some it is merely a convenience, rather than anything so meaningful.
To Gravel, however, divulging her real name to someone she trusts carries a very special meaning--that she is sharing her 'chattel' identity and her knight identity with that person.
This is a privilege even the Kazimierz family that endowed her with knighthood has not yet enjoyed.
