(See the summoner page on the Worlds of Adventure site for information on how the summoner class is modified from the Pathfinder version.)
For every 30,000 XP a summoner spends on epic abilities, she can switch out one of her spells known (of any spell level, from 0th to 3rd) for another one of the same level.
For every 10,000 XP a summoner spends on epic abilities, she can re-allocate her eidolon's evolution points.
