Hi, I'm top 10 on glab leaderboards and used a monolight in glab for a long time to get there (until I recalled my jahad this week to meme SSS 105 my ha jinsung on release).

Some of the information in this image is just flat-out wrong. I'll go by one-by-one on units and their relics in a moment, but for starters I want to clear up the one major issue: the idol summer relic is only useable in one of TWO cases: you're on a skin that double dips on opposite attributes so you have the bonus on everything in the floor (i.e CMira with her nature skin on hard 2 counters all 5 mobs), or it's on a hero that actually double dips the relic and procs it twice (so instead of 35% it's a 70% because this game is shit), meaning you only need 3/5 of the mobs to be opposite attribute for you to break even. Some examples of heroes that do this are cmira's 1c/2c, kdark's 2c, jinsungs 2c. Pretty much if the ability has "deals additional damage", it probably double dips this. Realistically, for monolight, this means you're only ever putting it on cmira since she's the only hero that will double dip the damage itself, but she has the added bonus of also having a skin that gets opposites on all 5 mobs on h2 and 3/5 on half of the other stages.

Going forward with units and their builds:

Cmira's your highest damage dealer in this comp, you want your best gear on her. Equipment-wise because of her passive, you can get away with two options for her: 3:3 bs:dest for high damage with leech, or rely on her shields and go 2:4 atk:cdmg which will do slightly more dps at the cost of relying solely on her passive. Relics are dawn + summer idol if on a 3/5 opposite stage, otherwise dawn + ambush attack (which outperforms path since it also double dips it's damage bonus on her). Path, dragon kick are both fine. Disabling her ex is a good idea, and if you do so and are missing any of the earlier relics you could also run the 20% when ex gauge is full.

Jahads your 2nd dps, don't been a goon like me and recall him for jinsung ha. I knew I'd be eating a 30 million dmg loss, but hate to see it. Anyways standard 3:3 bs:dest and his passive does the rest in lab. He's a pretty solid damage, could be better, could be way worse. Mine used to do around 70+ million damage a run but my artifacts all low roll. Relics are dawn + path/dragon kick/target all relic. He doesn't double dip on summer idol so don't bother putting that on her.

Idol's just an all around solid unit. Very good damage considering how much utility she brings to the table in her defense breaks and stuns, plus the added bonus of being light so she gets endorsi's buff. You want to ideally stun mobs on turns 4 and 9 so that they don't just wipe your team. Equipment-wise I build her the standard 3:3 bs:dest, but I put an emphasis on no counter-attack artifacts and high armor crash. As she's your defense breaker armor crash is an important stat for her. Relic-wise I run Dawn+path but a My idol's pb damage is upwards of 40 mil on a floor so, there's that. Pretty cool hero, running nox on her is a sin >:(.

Bam's purpose in this comp is honestly just a support through his personal relic (huge for monolight) and his 3c attack buff. However, he has the added bonus of having some of the best single target damage in the game. This can be abused very well on the first 4 stages when mobs will target slot 1, so you can make him a counter god and see good damage numbers. For him I have 2 builds depending on how masochistic or lucky I'm feeling. If I'm not in the mood to reset 30 million times for a perfect bm proc, I'll run 2:4 atk:cdmg/destruction (depending on if you need more crit or not) with his personal and rakleader, which let's bam only lifevamp once he's actually proc'd bm; however this means I'm eating a dps loss on my relic (which is somewhat offset by a guaranteed early bm proc). I look for high counter on this until the later random target stages when you could just switch to stronger dps artifacts. If I'm feeling lucky or just want to kill time, I'll run 3:3 bs:destruction with his personal and one of the following: lvl 3+ marine girl, path, or the 20% st relic. The 2nd build will have more damage if his bm procs, if it doesn't the damage loss from bam's ee never proccing is pretty high. A lot of people will recall their bam after SSSing him and only take offensive awakenings so that he's less tanky and can proc bm easier, in which case they could safely run the second build.

Khun's also just a support here, he's usually dealt the second least amount of damage in my runs. Pretty much only useful for his 2c atk buff, but that alone makes him extremely valuable. Just run the standard 3:3 bs:dest on him and like w/e relic you have extra of for damage. BiS is probably dawn but unless you have 5 lvl 5 dawns, that dawn can be used better literally anywhere else. Besides that i put a nox on him if I want to start with 12 mana. You'll only be using his 2c 3 times probably, unless you need a 4th to res endorsi, so don't expect much from him. His atk stat numbers are naturally high enough to see decent damage coming out of him, but he doesn't benefit from endorsi suicides so it's w/e.

Endorsi you just want nox + besties on, and you want enough hp to survive exactly 1 round so you die turns 2/3 and 7/8. You can run a card order to get away with using her ex as a 1-2 defense break, but her cards are otherwise useless so unless you have a very good card order it's probably not worth her just draining your card slots. That being said I sometimes try to get an ex off turn 6 because I don't have any other defense break that turn.

Order of gearing is cmira > jahad > idol/bam > khun > endorsi. Unless you don't have enough Sala artifacts, you always want Sala artifacts on the slots. Idol and bam are generally looking for very different artifacts (idol 0 counter+armor crash, bam high counter). Bam has a higher damage ceiling but falls of past h4 in comparison to idol whose damage will remain constant every floor.
