Hourglass is CDO2’s currency. You can use it to buy lords, buy cosmetics for yourself ( new profile pictures, themes ), or spend it to improve yourself by extracting hourglasses in secondary attributes. You can also use it to resurrect yourself when you die in your runs.

You can get hourglasses by redeeming codes, completing modes, 100% the archives, or the free hourly hourglass from the game’s shop.

Mana Extraction / Secondary Attribute:

The easiest explanation for mana extraction is that it can give you permanent buffs of various things as your secondary attribute for your future runs. ( e.g. max room control +1 ).

There are 4 extraction options.

Hourglass Extraction:

Self explanatory. You use your hourglass to extract either 1 or 5 cards.

Points Extraction:

Max use per day 3 times. You get 100 points after reaching 50 years in any mode. The max points you can accumulate is 500.

Challenge Rewards Extraction:

Upon completing challenges, aside from 100 points, you can also extract several cards depending on the challenge level you’ve just completed for free.

Ranking Rewards Extraction:

Upon completing the competition and getting your medal, you will get rank points based on your [Ranking Pt.]. Depending on how many rank points you have from your medals, you can extract that exact amount of points.

Game Modes:

Challenge Mode

you don’t get any additional rewards for going over the 50 years mark. every run gives you 100 points for extraction. selecting ‘delete’ for either of your modes will still give you the points.

Competitive Mode

You strictly compete with other players for your place on the leaderboard. unlike challenge mode, you don’t get any hourglasses for finishing the 50 years mark, but you do get 100 points.

Resets every week with a race restriction and custom restriction a race ban and a new challenge.
Rewards 1 – 3 hourglasses based on your rank.
