If you are keen on dungeon challenges and pursuing high damage, then a warrior, priest or mage may be your first choice. For players who like PVP battles, Ranger or Ninja will be ideal. Overall, Warrior can be considered as the first choice.
1. Red equipment (excluding weapons)
Updates happen quickly, so don't get too hung up on red gear (which is key). The main way to get red gear is through key battles (more on that later). Unless gold equipment is 15 levels higher than your current red (or dark gold) equipment, there is no need to change. The level of the red equipment found in the abyss treasure chest depends on the level of your solo secret realm, which can be seen from the illustration. Therefore, if you already have enough red items, there is no need to open the Abyss Chest. Red rings and necklaces are rare items. If you get these valuable items from the Abyss Chest, you will make a lot of money.
2. Red weapons
If you can get a red weapon through 30 free draws, just use it. Although the warrior's red weapon can be a bit tricky... but once upgraded to three stars, it will take a qualitative leap! In the early stage when there is no red weapon, it is feasible to use orange or purple weapons, but in the middle and late stages, you should at least have orange weapons. In the middle and later stages, the strengthening of red weapons will significantly improve your combat effectiveness (this is very critical), so buy as many weapon strengthening stones as possible, and don't be stingy with your diamonds and resources. In the early stage, even if there are no better weapons, there is no harm in strengthening them, because these weapons can also be used as upgrade materials for red weapons in the future.
3. Use of diamonds
In this game, the most scarce resources are blood ores and keys. Investing diamonds in these two resources is the wisest choice. If you fail in the early and mid-term levels, or die in the key battle, try to use resurrection coins as little as possible (resurrection coins are precious resources, like diamonds, they are never enough), so try to avoid using the resurrection function. If that doesn't work, challenge the level again or let other players attack the key first.
4. Key strategy
Keys are one of the main ways to obtain red equipment. Red keys have a chance to unlock red weapons fragments or finished products. In the early and mid-term, try to use keys sparingly and save them to prepare for upgrading key quality later. Since equipment updates quickly in the early stage, a suitable set of red equipment is enough. Remember not to over-consume your keys. When participating in other people's key battles, there is a limit to the number of rewards per day. Try to choose battles with additional attributes that can unlock additional keys without obtaining additional abyss treasure chests. For example, when you are in the 62nd level of the secret realm, the level 62 key you obtain (the key level is directly related to the level of the secret realm) can open a level 25 red equipment, but the abyss treasure chest cannot open such high-level red equipment.
5. Other matters needing attention
Be sure to bring resurrection coins when participating in key battles. If you are a player who opens the dungeon, not having resurrection coins means a waste of keys. However, for those players who "take advantage of the ride", withdrawal is not counted in the number of participations. Compared with the solo challenge, the key battle rewards for a four-player team are slightly richer, so even if you can complete the level alone, it is recommended to bring other players with you as much as possible. Don't take it lightly just because the boss looks easy in the early stages. The key battles in the later stages may cause you a lot of trouble.
