Endless Ragnarok summons let players equip and call forth summons with attack skills and support abilities; some can be temporarily controlled, and certain conditions can lead to primal bursts.
What Summons Add
Endless Ragnarok summons are one of the expansion’s headline systems. Official copy says players can unlock the ability to equip and call forth summons, adding a new dimension to battle strategy. The systems page describes summons as having unique attack skills and powerful support abilities.
That is enough to explain the system at a high level. It is not enough to publish a ranked list of best summons, cooldown optimization, or boss-specific summon timing without direct play evidence.
Primal Bursts
The official systems page also describes primal bursts. It names Proto Bahamut and Excavallion and says that once certain battle conditions are fulfilled, activating Skybound Arts with all four party members can produce a primal burst.
For players, the important early lesson is that Endless Ragnarok summons tie into party timing rather than existing as a separate collectible-only system. If you already understand chain bursts, primal bursts should feel like an expansion of the same party-action language.
What To Watch Later
Future Endless Ragnarok summons coverage can become more detailed after testing answers practical questions: which summons are available, how they unlock, what their support abilities do, which fights reward control, and whether specific summons pair better with certain party roles.
Until that evidence is stable, this page stays source-backed and avoids turning official marketing copy into fake precision.
