Gravedigger has 2 ways of dealing damage to your team.
- Gravedigger fires 2 drill missiles, which if left alone will deal massive damage to one or two of your Nikkes and also stunning them. These drill missiles can however be blocked by cover, i-framed and also destroyed by firing at them.
- In Phase 1 and Phase 2, Gravedigger unleashes its drill attack when you fail the first set of red circles and the second set of red circles, or fail 3 sets of QTE/red circles in a row. Drill attack from Phase 1 and Phase 2 could be tanked if your units have stronger gears (full T8 at least, slightly better gears for higher HP required for Water units like Poli and Viper) and have full cover+full HP. In Phase 3, Gravedigger unleashes its drill attack that pierces cover when you fail the first set of red circles or when you fail two sets of red circles in a row. Drill attack from Phase 3 will one shot your entire team and end your run.
In short, if you can destroy or i-frame the missiles, and destroy QTE/red circles to avoid Gravedigger from using drill attack, you will be able to full clear. These 2 are done by having enough DPS and/or having good aiming, which means healing/shielding are not needed for this boss.
It is recommended to have at least 1 Shotgun unit for this fight to have enough burst generation to activate burst whenever it’s off cooldown, and also at least 1 CDR buffer to have more frequent burst rotations.
Shotgun units are exceptional against red circles but can struggle to destroy missiles outside of full burst, switch to an AR or MG user (Scarlet/Modernia) and manually fire at the missiles to destroy them without full burst.
Red circles are much easier to deal with if you have full burst mode available. This means that you should seek to have full burst available right before Gravedigger enters the next phase, especially Phase 3 where you have to destroy the first set of circles.
This can be done by purposely delaying your damage when you are about to enter the next phase but still have 2-3 seconds of full burst mode left. You can simply fire at missiles or take cover, and only proceed to deal damage to send Gravedigger to the next phase when full burst ends, so that you have enough time to charge up burst gauge before the next phase begins.
Another tip is if the QTE circles spawns at the bottom, you should aim slightly higher than the circle appears to be, since the hitbox is still at the top. (Video proof below)
The core units here are Isabel, Liter/Volume and Dolla. Isabel is a Shotgun unit that when activating her burst, decreases duration of full burst mode by 5 seconds, allowing you to use burst more often. However, this also means a higher amount of CDR is required, therefore 2 CDR units have to be used. Dolla is the only B2 with CDR, therefore she has no replacements.
Volume can replace Liter, but you will need much better gears on DPS units to compensate the lack of ATK buff compared to Liter if you use Volume.
Sugar and Drake can be replaced by any other units that do good DPS (remember that you do need at least another burst 3 here though). Maiden, Guilty, Viper, Neve, Modernia and Scarlet are good replacements. (Pick 1 more Shotgun for better burst gen)
For Phase 3 using this team, you should aim to break 1 set of circles and fully charge up burst gauge during the 2nd set of circles when using Isabel’s burst. This will allow you to have full burst ready for the 3rd set of circles, where you should aim to break 3 sets of circles within the usual 10 second full burst duration, and charge up burst gauge during the fourth set.
Shotgun without Isabel (Most Recommended)
Liter/Volume, the usual B1 buffers providing CDR which is very crucial in this fight. Liter way better than Volume since Liter provides huge ATK buff while Volume provides crit buff which is very medicore.
Guilty/Viper/Rupee are the top options for B2, with Guilty and Viper being Shotgun units which help a lot with burst gen and breaking red circles. However, Viper is a water element unit, which means she needs better gears to survive a drill in Phase 2. (at least full T9 with a level 3 chest)
Rupee provides a decent ATK buff to team and also deals decent DPS which helps breaking red circles, but not to the extent of Viper and Guilty. Dolla and Admi can also be used for B2, as they provide useful buffs to the team, but they do poorly in dealing with red circles.
Sugar and Drake are the top 2 Shotgun options vs Gravedigger. Sugar is the more crucial unit here, provides max ammo increase to other Shotgun units, which enhances their ability to deal with red circles as they can reload less. Drake deals good damage and also provides ATK buff and more importantly hit rate buff, which helps to deal with red circles.
Modernia deals great DPS as a B3 who will not be using her burst here. She also deals with missiles extremely well, manually control her when you need to clear missiles but is not in full burst mode. The same goes for Scarlet, although using Scarlet means you cannot tank drill in Phase 2. If you use Modernia, DO NOT put Modernia in the middle slot as there seems to be a bug where she takes more damage from the drills and will die.
For Phase 3, you should aim to break 3 sets of circles within the usual 10 seconds of full burst mode and charge up burst gauge during the fourth set.
Scarlet Reload Speed
Core unit is Scarlet, who can shred red circles with her high ATK. She does has the weakness of needing reload speed, which is where the other 2 units, Admi and Privaty come into play.
Both Admi and Privaty provide reload speed for Scarlet, Privaty also provides a decent ATK buff for Scarlet.
Liter the BIS B1 makes her appearance again, providing huge ATK, CDR and other buffs to the entire team. Volume can replace Liter in terms of providing CDR, but you need much much better gears on Scarlet to compensate for the lack of ATK buff, as Volume only provides crit buff which doesn’t do much in this game.
The final slot should be a B3 Shotgun unit to provide burst gen. Drake is the top option, providing decent ATK and hit rate buff without using her burst. Sugar and Maiden are 2 other options that will work too.
If your Shotgun units are stronger and your Scarlet is relatively weak, you can look to transition into the Shotgun without Isabel team instead and use Scarlet as a good DPS unit that helps to deal with missiles.
Noah Cheese (For Stage 7 with weak gears)
This team is used particularly when you have lower DPS due to weak gears (T7 and T8) and have relatively poor aim, where you are unable to get through Phase 2. You can of course full clear with this team, but that will require better gears, and with better gears, using the other teams mentioned before should be better anyway.
Core unit is Noah, allowing you to tank a drill from Gravedigger without taking any damage every other burst rotation. This means if you have full T8 and full cover, you can tank 1 drill using your HP and cover, and tank another drill using Noah’s burst. This should buy you enough time to deal enough damage to get past Phase 2.
Liter/Volume, the usual CDR buffer with Liter being much better since Liter provides huge ATK buff.
Guilty is a Shotgun unit that deals great DPS which helps to break red circles. Poli is a good replacement being a defender unit, which means she can tank a drill with full T8 (level 3 chest might be required) despite being a water unit. Viper is not recommended here as she requires full T9 and a level 3 chest to tank a drill. Use the other teams if you have strong enough gears that allow Viper to tank a drill, since it is very likely you can go through Phase 2 the normal way, not requiring Noah’s burst to do so.
Sugar and Drake roles are explained here. Maiden and Modernia are decent replacements here since they both do decent damage and can tank a drill with weaker gears.
The classic shotgun is ok when you have T9/T10 gear fully equip but for regular player or F2P just go for scarlet reload speed seems much better on my experience 🙂
what if i don’t have scarlet?
im just gonna auto this boss till they fix the unbreakable weak points
Every guide on this site: Get Scarlet lol.
In the Scarlet Reload Speed, you can replace Scarlet with Sugar and the result will be no worse, but rather even better than with Scarlet
what cubes do you need to use for shotgun team?
Resilience on Shotguns, Bastion for remaining DPS units
Tried following the SG Isabel comp but I’m still failing. Any ideas? Also tried Scarlet reload but without Admi, and yeah it’s not also going well lmao.
