How will the e20 System handle experience points?
Ideally, a character will need to participate in about 10 encounters to gain a level. We are using level-independent experience awards (Unearthed Arcana) because this allows the Game Master to use some encounter-building shortcuts similar to those used in 4E (e.g. using an “XP budget” that makes it easier to mix challenges of different levels). Here is an early draft of what the experience chart might look like; it shows challenges of up to 30th level for the sake of completeness and to account for the possibility of truly epic battles.
