Not sure where to go with this thread, but I just felt like listing out some random facts that I though would be interesting to know.
1. When equipping a support eidolon, the stats from that eidolon boost your team's stats as well. edit: This fact has been disproven (Slashley, Dreamlitz)
2. Eidolon episodes remain even if you sell her and no longer have her in your inventory
3. A player can join a union halfway through a union event and still claim the rewards at the end
4. Union guardian effects has its own damage multiplier
5. Diabolos Unleashed and the Lilims can lose their passives halfway through battle when there are no longer 3 members of different elements on the field
6. Healing is based on a percentage of a Kamihime's total health, it just has a low cap that can be easily reached
7. All burst damage buffs are stackable edit: Michael's ab2 and Shingen's PF buffs are stackable with other burst buffs, but cannot stack with themselves (ex. you can't stack two PFs). Also, Marchosias and Mike burst buffs do not stack (Dreamlitz)
8. Elemental resistance debuffs affects proc rate as well as lowering defense
9. Raid tickets do not roll over and are linked to the event from which they were obtained edit: Raid tickets are deleted by the next event IF they are in your inventory. If they are in your gift box, then they can be claimed at any time for any event (Slashley)
10. Healing from Kamihimes and Souls are capped, but potion heals scale indefinitely edit: El's regen is an exception to the rule (Dreamlitz)
11. Barrier can save a kamihime from the "insta-kill" affliction edit: Barrier can save a kamihime as long as the barrier + remaining HP is higher than the max HP (Dreamlitz, Rohtang)
12. The 500% burst damage cap can be bypassed by characters like Uriel and Metatron, who have other ways of increasing burst damage
13. Soul weapon effects still apply through energy inheritance as long as the legendary soul's abilities are selected
Some of this is common knowledge, but I'm sure these are facts that a lot of new players are unaware of. I'm sure theres a lot of obscure facts I missed, so add them to the thread pleaseee
