Experience (XP) is required for a character to level up and gain skill points. Experience can be gained in a few different ways:

Killing creatures - The amount gained is proportional to the type of creature, difficulty level, and wave. The character gains XP from both hero and tower kills. On the PC version, experience from killing creatures is not shared among the entire party.

Awards - Small to large XP bonuses for completing waves, various tasks and accomplishments. End of Wave bonus provides much of the experience gained on a map. The higher the wave number, the higher the experience bonus. The XP gained for completing a wave and the time bonus are shared among the party.

There is a limit to the number of skill points that can be used for a particular attribute: 985 for PC, 120 for consoles and 60 for Mobile.

Note: Experience tables may vary on version.

Relation between Experience and Difficulty

The chosen difficulty setting acts as a multiplier to the map's XP payouts. Using The Ramparts as a testing grounds, the following multipliers can be estimated.

Difficulty XP compared to normal Easy 0.5x Normal 1x Hard 4x Insane 8x Nightmare 20x

Since exact XP payouts depend on awards as well as completion time, some deviation is to be expected. Higher difficulties also tend to spawn more enemies, and enemies also have an increased base movement speed, causing them to reach player defenses faster. Nightmare also adds Spiders, Djinn, Sharken and Goblin Copters, along with their Ogres, to maps that don't normally have them.

Hardcore mode acts as a separate multiplier of about 30%.

Since base XP is ultimately dependent on the map being played, the difficulty setting is only of secondary importance. A later map like The Ramparts will still give considerably more experience on Hard than an earlier map like Alchemy Lab on Insane.

As a rule of thumb, late campaign maps and DLC maps have higher payouts, both in terms of XP as well as loot, than early ones.

Conclusion

When leveling, players should choose the latest map they are comfortable with and play it on the highest difficulty setting they can reliably beat, avoiding damage to both themselves and Eternia crystals for the respective bonuses. Since combat is to be avoided, it is recommended to enable Hardcore mode as well. Campaign mode generally has much higher end-of-wave XP payouts than survival mode, making it preferable for XP farming. On Insane and Nightmare difficulty, however, build timers will need to be taken into account.
