The Abyss is one of the game modes in Blades, consisting of a dungeon with infinite levels. Each level has a small amount of monsters facing you and as you clear your way through Abyss, you are periodically offered rewards. The monsters will gradually become harder and the rewards will increase[verification needed]. Contrary to the regular dungeons that you explore in Blades, Abyss contains no healing items or other rewards apart from the fixed rewards for clearing certain amount of levels.
When you exit the Abyss, the next time you are offered to either continue from the level that you stopped at, or start over from Level 1. Upon leaving the Abyss you can also see some stats about how far you managed to explore, how long it took, how many monsters you killed, and which rewards you managed to claim.
There are various Challenges tied to exploring the Abyss, such as dealing damage or using a certain amount of combined attacks while in the Abyss.
You unlock a level of the Abyss by making it to the next level. You can always start from the last level you unlocked, from level 1, from your character level if it is less than the last level you unlocked, and from any multiple of 5 less than the last level you unlocked. If you are level 18 and have reached level 22, you can start on levels 1, 5, 10, 15, 18, 20, and 21.
While in the Abyss, once you pass a level and get the rewards you cannot return to the previous level. The stairs will be blocked.
There is a reward of gold and experience for each level passed. The reward is given no matter how many opponents are defeated. The reward shown as you pass each level is the total for all levels passed on this trip through the abyss, not just the current level. If the reward is 200 on one level and 300 on the next, that level added 100 to the total reward.
There is an item in the corner with a ring around it. Killing enemies fills the ring. When the ring is full you earn that reward and a new reward is shown. The first few rewards are common materials, then a wooden chest, and eventually equipment, gems, and golden chests. The ring will fill more for some opponents than others and is affected by the reward multiplier for high levels.
As with chests, the rewards depend on your character level. The rewards do not depend on the level of the Abyss, but the harder monsters on deeper levels will fill the ring faster so you can reach the better rewards. Each new trip into the Abyss resets the rewards gained. The first few rewards will be common, then slowly have a chance to be uncommon or rare.
The first kill in the abyss always grants one reward. It is not the reward shown in the ring. It is usually an enchanting ingredient.
Any opponent that might normally drop gold will also drop gold in the Abyss, but nothing else will be dropped.
When you reach a level of the Abyss higher than your character level, all gold and experience rewards have a multiplier. At one level higher than your character level, the multiplier is 1.25x. After that, the multiplier is the number of levels higher than your character level. If you are level 12, then at level 15 there is a 3x multiplier on all rewards.
Opponents on levels above your character level also become more difficult. It may be that their hit points or other attributes have a similar multiplier.
At levels lower than your character level, there is probably some penalty but it isn't clear.
Most levels of the Abyss have 2-3 enemies of one type. Pack animals like Skeevers or Wolves will usually have 2-3 packs of 2-3 creatures each. Some enemies, like Warmasters and Dragons, may be alone on a level. Some enemies that naturally go together, like Outcasts with Liches, Wolves with Bears, or Wisps with Mothers, may show up on the same level. Enemies like Goblins and Dremora Raiders that have more than one kind will usually be mixed together.
Deeper levels of the Abyss have rarer creatures. Starting around level 20 there are Liches and Warmasters. Starting around level 25, there are Dremora Raiders and Dragons.
