The following is a list of the experience granted per sunk ship. The left number refers to the sum of the relative level of the ship compared to your ship and the relative level of the ship's captain compared to your level, the middle number is the experience granted, and the right number is the experience for a mission kill (half). NPC captains are the same level as their ship. For instance, a level 20 captain in a level 20 ship sinking a level 22 NPC would receive 210 experience (22 - 20 = 2, 22 - 20 = 2, 2 + 2 = 4), but a level 20 captain in a level 17 ship sinking a level 22 NPC would receive 230 experience (22 - 17 = 5, 22 - 20 = 2, 5 + 2 = 7). Within missions, the above kills would result in 105 and 115 xp, respectively.

All members of a group present in battle when a ship is sunk gain xp for that kill. This xp is based on a fraction of the xp they would get from a solo kill, with the specific fraction based solely on the number of people in the group. This fraction is calculated from an idea "bonus rate" of xp gain... the multiplier to individual xp gained over time if each member of the group performs equally well. For example, the multiplier of 3x for groups of 5 means that if a single captain could sink one ship per minute while soloing, and five of them together sank five ships per minute, each of these five captains would recieve three times the experience they would have recieved if they were working on their own.
(Fractions in the table below are rounded)
| Group Size | Per-kill Fraction | Group Multiplier |
|---|---|---|
| 1 | 100% | 1x |
| 2 | 75% | 1.5x |
| 3 | 66.6% | 2x |
| 4 | 62.5% | 2.5x |
| 5 | 60% | 3x |
| 6 | 58.3% | 3.5x |
Killing NPCs in Swashbuckling missions grants 1/10 of the xp the same kill would have given if it were a ship. For example if you are level 20 and kill a level 25 npc avatar you get 25 xp, 25-20 = 5, 5 from the list above means 250 xp, 250/10 = 25. Note that killing npc crew or captains in boarding combat grants no xp.
The following is the experience needed per level. The first number refers to the captain's level, the second number is the experience to get to that level from the previous one, and the third number is the cumulative experience required to get to that level.
