※ Guaranteed Summon System Information
1) The Guaranteed Summon System will only be applied to limited summon Drop Rate Up banners.
2) When players summon a hero during the banner, the summon counter will decrease by 1 for each summon that does not yield the banner hero.
3) If the hero has not been summoned after a certain number of summons (in this situation 120) then the next summon is guaranteed to be the banner hero.
4). Summoning the hero in the banner will reset the hero counter back to the original number.
