OFFICIAL SEALSTONE LIST is here. Start making your teams, zomg!
Unless otherwise noted, these affect all combatants, enemy and ally alike. You may also only choose one per team and may not change this throughout the dungeon.
Life - One character's healing effects now also allows for revival, but reduces the final effect of any healing to 50%, regardless of how strong the healing was before. The healing also only revives characters with 1 HP.
Speed? - The effective speed of one character is reversed, but after the first round of combat, their speed returns to default and can not be increased in any way.
Resourceless - Your spells and abilities are now free but you may not use the same ability more than once a fight. This does not apply to moves that drain all resources.
Multitarget - One person on the team's actions all become Multitargetted. However, the damage, healing, chances or stat effects of these effects is reduced by 50%. (For example, Deadly Fingertips has a max 50% chance of hitting all targets.) This applies even if there is only one character.
Violent Burst Law - Characters with system-specific gauges begin the floor with them filled. These gauges do not charge during the floor by any means.
Status Symbol Law - ALLY Team is fully status, debuff and ID immune, but has all their total statistics reduced by 15%.
Love Love: Damage is increased by 50% against same-sex targets and reduced by 50% against different-sex targets. This applies to both enemies and allies.
Elemental Advance Sealstone: Each attack of the same elemental type is used after the last one, it gets a 25% boost. Both sides may take advantage of the same level of damage, but also break the chain with an opposing spell.
Vantage Effect Sealstone: Counter abilities excecute BEFORE the attack that triggers them for all enemies and characters.
Firefly: A chosen member of your party will always be the target of enemy attacks. However, this also bypasses normal immunities (so no Gastly avoiding physicals this way) as well as status or elemental immunities. The character is still the target unless hit by a fatal status. This does persist if the character dies and is brought back to life. However, multitarget moves ignore this effect.
