The damage calculated varies from condition to condition.
Bleeding Formula:
2.5 + 0.5 * Level + 0.05 * Condition Damage per stack per second
Poison Formula:
Level + 0.1 * Condition Damage per second
Burning Formula:
4.1 * Level + 0.25 * Condition Damage per second
Confusion Damage:
25 + 0.5 * Level + 0.075 * Condition Damage per stack per skill use
The story mode is actually a side story, an add-on to the personal story. Explorable mode is usually providing harder quests in the same dungeon.
Most dungeons have 1 path in story mode, and 3 different paths in explore mode. There are exceptions to this rule, however.
- Twilight Arbor doesn't have 3 clear paths since the beginning to choose from, but has in fact 1 or 2 intersections. The possible paths still sum up to 3, though.
- The Ruined city of Arah has 4 explore paths, instead of 3.
- The Fractals of the Mists is particular, and is actually composed of 9 mini-dungeons. A run through the Fractals will pick a combination of 3 of those mini-dungeons, to which will be added a fourth one (fixed one), if the difficulty scale is an even number.
So if we sum it up, it makes seven "regular dungeons" with four paths (1 story + 3 explore) and one with five paths:
7 x (1+3) + (1+4) = 33 different experiences from the regular dungeons.
The fractals can be counted on several ways.
Technically, there are only 9 different zones. However, if you count each possible combination as a different instance, the total goes up to:
9*8*7 (for uneven numbers)
+ 8*7*6 (for even numbers)
= 840 different dungeons
If you want to be particularly specific on anything which defines a "different" experience, you could account for the difficulty level (80 of them), as well as the order in which the combinations come (and multiply by 6), which would leave you with a total of...
403200 "different" fractal experiences.
But that would be slightly exaggerating.

From the recent update, each player gets awarded an extra 40 tokens on top of the usual 20 for each dungeon route he takes in a day (doing three times the same dungeon with the three different routes will give you 180 tokens).
However, update had bugs. Some players were considered to exploit the dungeon and get rewarded only 15 tokens for their first dungeon (then 6), and others only 30. (Behaviour has been corrected since the 2nd of October)
There have been rumors that these players would get their tokens back in a future update, but only if they have reported the bug (these are rumors). It is recommended to send bug reports when this happens and you are still in the dungeon (type "/bug" in the chat).
I personally only receive 15 tokens on my first dungeon and report the bug each time, in case the update would give me the missing one back.
