New Players Guide

Pre-Baal
Your first goal in the game is to beat the tutorial/beat Baal. You will want to create as many shadow clones as you can, because every 20 clones created or killed will increase your "soft cap" from 1000 gradually to 99,999. You want to rebirth when your rebirth multi is decently higher than your current multi, at least 100x. You should always be either automatically or manually training special fights, so that it takes fewer clones to train phys and skills.

Easy early pets to unlock are Cupid, Frog, Bee, Egg/Chicken, Mouse, and Bug (Pet). If an event is going on, you should run the event campaign and spend the pet token on Thunder Ball/Raiju or Pandora's Box or Otter. When you have your first six pets, you can put them in Newbie Grounds as a dungeon team. It takes 1.5 hours to reach the boss. You can create your first dungeon team within a few days to a week of starting the game, since all of these pets are unlocked by Zeus. When your pets have reached around DL10, you can move them over into Mountain Dungeons D1 0/0/0.

As soon as you unlock monuments (after beating Diana), build them. Before you defeat Nephthys, build monuments as high as you can. After Nephthys, you can buy creations, which makes it much easier to get enough of them for cheaper monuments. Mighty Statues and Mystic Gardens are really good to improve stats for your current rebirth, especially after you can upgrade them (after beating Freya). The more expensive Monuments are better for your rebirth multipliers, so it is good to upgrade them before you rebirth, after you have your divinity generator.

After you beat Cybele, you can get all creations you need to unlock the Divgen. To do that, you need to build at least one Monument of all up to the Temple of God. Newer players often underestimate the power of the Divinity Generator, but it can speed up your progress a lot. You basically put in creations and the get more divinity back than it costs to buy your creations, which multiplies your divinity, and so the creations you can buy. You should always keep it filled after you have it. At the beginning, upgrading the divinity generator is really slow and might not be worth it. When you have some more building speed and 100k+ Clones it might be worth it to upgrade it a bit.

Your first ~150 GP can be spent on raising your CS to 345%, getting a bit of BS, buying one Creation Count so it takes less than an hour to create all your clones, and buying another 10,000 clones.

You should be opening as many lucky draws as you can. If you are playing on Android or you have purchased the ad pack, ad points should be spent on lucky draws for now. Lucky draws have the chance to contain pets or other rewards.

By the time you have ~50,000 clones, you can start training might. Might unlocks once you've trained all your skills. It takes at least 94 minutes, and longer if you don't have enough clones to one-cap your skills. Might gives you boosts in your current rebirth and there is a lifetime counter of all might you've ever gained that gives you a boost across all your rebirths.

If you want to make premium purchases, good ones here are the refrigerator, daily packs, or a pet token. Buying GP will speed up early progression if desired.

First Baal Kill
By the time you kill Baal for the first time, you should have unlocked Armadillo and Squirrel. You will gradually be gaining materials in Mountain dungeon, looking towards evolving Frog. If you would like, you can play the Pet Card game to earn food for your pets or to give to Mouse for its evolution. You may have enough ants to evolve Bug.

You have a rough idea of game mechanics now, and it's time to start your first challenge. This is an Ultimate Baal Challenge. A UBC is something like resetting to when you first started the game, but without the Newbie Boost. The good news is that you keep your one-caps, and you have a better idea of what you're doing. Your pets do not provide multiplier, but they can still spend time in dungeons. You can move up a dungeon difficulty level whenever you beat the boss in less than 15 turns and are not dying.

Your first UBC may take you a week. That's OK. The later ones will be faster. If you're going to whale, GP purchases go a long way here.

When you finish the UBC, you'll get your GP back and bonus GP as a reward. You get to keep any might that you trained during the UBC. You may want to buy Improved Next At by now so that you can have your clones automatically move to the next training. Good GP purchases here include more shadow clones, more BS, and one more CC. As a rough rule of thumb you should aim to have enough CC to create all your clones in 20 minutes.

You should be able to evo Mouse and Frog by now. The mouse is a wildcard, so you can make it anything you want - Supporter is usually a safe bet. Frog is a supporter. You should usually evo pets to whatever class they get a bonus for.

By finishing your first UBC, you have unlocked the Crystal Factory.

If you want to make any premium purchases, this would be a good time to get the crystal to improve upgrade or unlock more crystal slots.

Post-UBC
Your second challenge should be a Day Pet Challenge. You will get at least a 20% bonus for feeding your pets just by waiting one day and making sure they are fed. Train your pets for a while and don't worry too much about how you're doing.

If you are able to create an Earthlike Planet, you can start using the Crystal Factory. Killing Planet Eater - use all your clones, and Planet+ Might - will give you 100 energy, which you can use to buy one creation module. The module will take ten minutes to produce one crystal. That crystal will raise your creation count. You can max your crystals at the end of the rebirth and they will provide Crystal Power, which persists across rebirths.

After the DPC, you can go into Double Rebirth Challenge. This is much easier than a UBC. It resets your multis, but you keep your stats and your pets. The goal is to kill Baal. You should notice that it goes much faster this time around.

At some point, you will have your first 50 Challenge Points. Spend it on damage reduction vs UBs.

After your first DRC, you can do your first God Power Challenge to unlock the pet. At this point, you will be up to at least 500 lifetime GP and should have a basic idea of how to play the game. A good idea here is to continue to go through your DRCs.

The community has made a challenge order guide that gives a safe walkthrough of which challenges should be completed and when. Do not take this as law, and feel free to experiment with challenges. You can always cancel out after an hour, so don't be afraid about losing progress. https://docs.google.com/spreadsheets/d/1tsG02nUjt5SZrtaXZkJmqwg9TpZ23KidxBgBUy7um0A/edit?usp=drivesdk
