RO635

Overview

RO635 Mod is a 6-star SMG mod that becomes available with the major event Dual Randomness. Wait… she’s not even using the same weapon anymore? What’s the point of the codename then?!

She boasts extra parts to her Skill 1, higher base stats, stronger tiles, an extra 10 evasion from her SOPMOD inspired special equipment, but most importantly a stupidly strong tanking Skill 2 that makes her one of the best SMG maintanks in almost any situation.

RO635 Mod’s Skill 1 gets a 10% enemy accuracy debuff on Mod 1. Combined with the rest of the skill this counts as 2 debuffs for her Skill 2, as well as lower damage taken even if it hits.

The Skill 2 applies a Seal of the Avenger (yes the same one as M4A1 Mod’s) to enemies RO635 Mod is attacking when her Skill 1 is up, also counting as a debuff.

Whenever RO635 Mod fails to dodge an attack, she will have a chance to retry dodging the attack. This “second try” is not an additional flat evasion chance like rumored, but actually comparing RO635 Mod’s evasion to their accuracy and making the proper calculations. The base chance to activate the passive is 20%, and it goes up by 10% additively for every debuff the specific enemy that she failed to dodge currently has. (E.g. RO635 is attacked by an enemy with 2 debuffs and fails to evade. She now has a 20% + 10% + 10% = 40% chance to try evading the attack again.) Keep note this is not all debuffs, but specifically the Firepower, Accuracy, Rate of Fire, Movespeed, and Seal of the Avenger debuffs.

Now for the important part. For some reason, this second chance also applies to normally sure-hit attacks such as grenades, rockets, lasers, electricity, taxes, fire, and snipes like from doppelsoldners, Jupiter cannons, typhons, minotaurs, the IRS, archers, and SWAP jaegers. Even if they are normally undodgeable, every enemy has its own accuracy stat. So RO635 Mod throws that out of the window. Obviously, she fails her first evasion check since these attacks are undodgeable. But then, if she gets to activate her passive, she does an evasion check against that enemy accuracy stat and STARTS DODGING EXPLOSIONS.

Needless to say, this is quite useful, and potentially lets RO635 Mod replace roles that force shield dolls took up, due to also being able to ignore the damage. It being passive means that RO has the distinct advantage of having constant uptime on her passive rather than the 4/16 of force shielders and lets her be relevant in late-game content when these kinds of attacks are everywhere all of the time.

Even against attacks that can normally be evaded, this is estimated to be about a 500% self-evasion buff with some added sources of debuffs. Her effective HP soars above other maintanks. Her tile buffs might not work well with certain ARs, making UMP45 Mod more effective in DPS-reliant fights, but RO635 Mod offers consistent survivability.

Pursuing a 100% chance to activate RO635 Mod’s passive (8 debuffs) is difficult and usually not recommended, but adding 2 or 3 and plenty of evasion buffs can be plenty enough to make her supremely hard to kill.

The most value RO635 Mod gets is in her second skill, so leaving it at Mod 2 is alright, but the extra 10 evasion from her Special Equipment and the extra Evasion increase at level 120 might come in handy for her, so taking her to Mod 3 is not out of the question.

But at the very least raise her. She’s good. That is all.

Strengths

Dodges Explosions

RO635 Mod can avoid sure-hit attacks, widening her available team positions to include even those usually taken up by forceshielders.

Strong Survivability Skill

The bonus 70% evasion, 25% less damage taken, and 10% less enemy accuracy do wonders for RO635 Mod’s ability to tank, even against enemies with good accuracy. It also synergizes well with her Skill 2 by counting as 2 debuffs and increasing her dodge chance.

High Base HP

1040 HP is very high for SMGs, and lets her Skill 2 encompass a lot of enemy attacks due to high link HP.

Low Initial Cooldown

RO635 Mod’s 3 second initial cooldown is much shorter than a lot of high-survivability tank skills, letting her avoid taking significant damage early on from before the skill kicks in. This is good for close-spawning enemy formations.

Weaknesses

Low Active Skill Uptime

RO635 Mod still has the same 5/12 uptime issue of her base pre-mod form.

Incredibly High Damage Attacks

Very few attacks actually do more than 208 damage to a single link, examples including Hydras, Golyats, and some boss attacks. But these attacks completely bypass her Skill 2, and are too much for even RO635 Mod to take face on.

Team Options

Some Modded Anti-Rain Team Members

Due to RO635 Mod’s skill 2 applying Seal of the Avenger and counting it as a debuff, she has synergy with some members of Anti-Rain in their modded forms.

Debuff Sources

Some HGs give debuffs without sacrificing DPS. There are also those among HOCs, SMGs, and ARs that give them too. 1 or 2 extra debuff sources without sacrificing significant DPS would be helpful.

Evasion Buff/Accuracy Debuff Sources

In order for RO635 to tank both normal attacks and unavoidable attacks well, her dodge chance can be raised higher to improve her survivability. This is usually achieved using tiles or parts of a skill. However, still, do not sacrifice DPS.
