The Seal Talisman had no damaging effect, but it brought this one minute of status effect.
What did one minute mean in Glory?
A 1v1 duel where one side was much stronger than the other would generally end within one minute. When the two sides were relatively evenly matched, then it would depend on the players' individual habits and styles, so time duration wasn't a good statistic to keep track of. Still, assuming the characters met in direct confrontation, it would usually take over 3 minutes to determine victory.
Ye Xiu, in his individual matches, typically played with this kind of rhythm, and this match with Ge Caijie was the same. After they had each tested the waters, the two of them began fierce combat.
