Seal prohibits the victim from using Combo Skills for a short duration. The duration seems to always be 1 round but the exact timing is unknown especially when the Seal is applied in the middle of a round.
To be explicit, it does not prohibit:
- Resurrection effects like the one granted by Shadow Dragon's cannon as this is not considered a Combo Skills
- Further effects upon resurrection like "Reborn from Fire" from Phoenix's cannon.
Seal is usually visualized on screen through a purple effect that includes chains. The effect can however easily be missed when watching the combat animation as its display can be quite short. Note also that some other effects can have the same visual without creating a Seal, at least one of the Super clones' special attack does.
