Leveling system

The leveling system of Doctor Who: Legacy involves the accumulation of experience among a player's companion characters, as well as the expenditure of time fragments to rank up both companion and Doctor characters.

Levels

Each companion has a level, indicating its progression. Higher level characters have higher attribute values, while the Doctor's attributes are based on the average level of companions included in the team.

Leveling up

To level up a companion, that companion must accumulate experience by being included in a team while clearing game levels. Companions that gain enough experience will level up, which increases their base attributes and grants an additional point to distribute among the character's three attributes.

Companions can also be leveled up to the max level for their rank by spending time crystals.

Experience tracks

Each companion fits into one of various experience tracks. The following table lists the cumulative total amount of experience needed for a companion on a given track to reach a given level within each rank, accumulated during that rank.

Maximum level

A character reaches the maximum level for its rank every ten levels; after that, it needs to rank up before it can level up again.

Ranks

A character's rank determines the effect and charge time for its power. Companions of a given rank are also restricted in leveling up; every ten levels, a companion will cease to accumulate experience and stop leveling up unless they are ranked up.

Ranking up

To rank up a character, the player must do one of the following: (a) spend the appropriate number and colors of time fragments using the Upgrade button; or (b) spend a number of time crystals using the Instant Upgrade button. Companions must be at the maximum level for their rank in order to rank up, regardless of the method used.

The colors and number of time fragments required to rank up a character varies depending on the current rank and whether the character is a companion or a Doctor. On all ranks (except rank 5 for doctors) the time fragments of that character's gem color (Type A) are required. Until rank 5, the time fragments of the gem color that's weak against the character's gem color (Type B) are required, too. In addition, on ranks 2 through 4, pink time fragments are required.

After rank 4 (rank 5 for doctors), instead of pink fragments, special additional fragments (Type C) are required. These are either the Omega (for red, blue and green characters) or the Rassilon (for yellow and black characters). Additionally, after rank 4 Doctors need Infinity fragments.

Finally, all characters need strands of time to upgrade from rank 5 to rank 6. Not all characters can already be updated to rank 6, but this possibility will be added continually for the remaining characters.

Rank	Needed to Upgrade
	Companion	Doctor
1 → 2	2 Type A, 2 Type B	3 Type A, 3 Type B
2 → 3	6 Type A, 6 Type B, 6 Pink	8 Type A, 8 Type B, 8 Pink
3 → 4	10 Type A, 10 Type B, 10 Pink	12 Type A, 12 Type B, 12 Pink
4 → 5	20 Type A, 20 Type B, 20 Pink	12 Type A, 12 Type B, 12 Pink
4 → 5	20 Type A, 20 Type B, 3 Type C	25 Type A, 25 Type B, 5 Infinity
5 → 6	20 Type A, 5 Type C, 1 Strand of Time	5 Type C, 5 Infinity , 2 Strand of Time

Maximum rank

A character at maximum rank is unable to rank up any further. Currently the maximum rank is 6.
