RIIC Base Skills






Botzu's Quick Evaluation
+ Robotters are very cheap to deploy.
+ S1: Makes Robotters quite tanky. Nice dodge buff for adjacent allies at higher Skill levels that stacks with other dodge buffs.
+ S2: Can dish out a ton of damage if you use multiple Robotters
- Robotters count toward the deploy limit
- Requires significant resources to get to the point where she is useful endgame
Operator Overview
"If anything breaks, I can just make another one!"
Busy-body inventor and one-person army, Mayer is a Summoner Supporter Operator who can stall enemies and provide large amounts of on-demand Arts damage nearly anywhere on the map.
Mayer’s playstyle revolves around her unique trait, which allows the placement of ‘Robotters’, which she calls her Meeboos. Robotters act like melee Operators, can block 1 enemy, have decent HP, and decrease the ASPD of enemies that engage them. Robotters count toward the Deploy Limit, and are restricted in the number that can be deployed, which increases as Mayer receives Elite promotions.
Mayer’s first Skill, Bionic Device, passively increases the Physical and Arts dodge chance of deployed Robotters. Although heavy investment into Bionic Device allows Meeboos to extend this buff to nearby allies, and can be stacked with other dodge buffs, this Skill is primarily a stalling tool. It is Mayer’s second Skill, Detonate and Recycle, that is the game-changer. Detonate and Recycle self-destructs all deployed Robotters and deals massive AoE Arts damage, briefly stuns surviving enemies, and ‘recycles’ all detonated Robotters. This allows them to function not only as strategic low-cost blockers, but also as nuclear Arts bombs that can bring pinpoint mass destruction to almost anywhere on the map.The recycling functionality enables rapid redeployment for quick alteration or reconstruction of defensive lines.
By design, Mayer as a standalone Operator is underwhelming due to her very low stats. However, with skillful utilization and placement of each Robotter, Mayer can be a one-woman wrecking crew and even single-handedly clear missions. Learning and experimenting with Mayer’s capabilities will be well worth the time spent with this uniquely versatile Operator.
Elite Promotion Discussion
Another Operator whose Talent is core to their mechanics. The number of Meebos that her talent Robotter allows to be deployed increases from 4 to 5, a significant increase if you want to use this one-woman-army to her fullest potential.

Base Skill Analysis
Mayer gains her second RIIC Skill at E2.
If you are planning on using this niche Operator at her full potential, then you will need to E2 her eventually. The Skill she gains is the best non-specialized buff for the Factory. Since Factory buffs are always in demand, it will be a nice addition.

Appointed as Assistant | Structural design, industrial R&D, scientific research. You name it, and I can do it, Doctor. |
---|---|
Talk 1 | The Engineering Department never approve my proposals. Do they have any bias toward me? What should I do... Right! Doctor, would you please submit this suggestion on improvement for me? It's a deal then! |
Talk 2 | There are many workshops like mine in Rhine Lab, but what takes others six weeks to finish, I can have it done in one. I'm not boasting! |
Talk 3 | DO NOT interrupt me when I'm doing my research, or you'll have my Meeboos on your ass! And me! |
Talk after Promotion 1 | At night I'm always full of inspiration... and the urgency to sleep! No... I can't bear it... Where's the pillow... I need to rest... |
Talk after Promotion 2 | Hm? Why are these cuties called Meeboos? That's because they go "meeee-boooo" when they boot up. So I named them after that. Fitting, don't you think? Just listen and you'll get it. You press this switch to... WHUAH?! Wrong one! That's the self-destruct button! Oh shoot, run awaaaaaay! |
Talk after Trust Increase 1 | That girl who just passed by... that was Silence, right? If only then... Oh, sorry, the non-disclosure agreement is still in effect. I should keep my mouth shut. |
Talk after Trust Increase 2 | I feel kinda empty when I've got nothing to do... I guess that's just how engineers are. You know how that's like, right, Doctor? Huh? You don't? |
Talk after Trust Increase 3 | Doctor, may I request... No! Not 10 square meters! I asked too much last time, so this time... all I need is 3 square meters! Don't... Don't you leave, Doctor! Even 1 square meter for my research will do! Please! |
Idle | Geez... where's the coffeemaker... Oh, there it is... You want some too, Doctor? |
Onboard | I am the Lutra Workshop of Rhine Lab, at your service. Yup, I said "workshop," but it's just me. I'm the whole workshop. Am I amazing or what? |

Promotion 1 | This raise came just in time! I can afford to upgrade my equipment now. |
Promotion 2 | I promised I'd show you progress one day, didn't I? Look at what I have! Isn't it nice? |
Added to Squad | Time to go, Meeboos! |
Appointed as Squad Leader | Commanding both Operators and my Meeboos at the same time is a bit much even for me... |

3-star Result | Nice! We practically rolled over them! |
Sub 3-star Result | The device is slightly damaged. I'll fix it in no time. |
Operation Failure | Oh no! My Meeboo...! I'll need to make more... |
Assigned to Facility | Now I want a new workshop! |
