I don't know about others but I wasn't looking forward to this because Bonz is lame and his rewards are too. However, he has been very generous with dropping skills for other characters.
I know that it is probably due to the campaign bonus, but Bonz in particular has also been generous with me when it comes to rare drop skills. Last time, it was Harpies' Hunting Ground, this time, Last Gamble.
That's great. Only good skill I have got that I wanted was 3SD. Otherwise I got heavy starter, draw sense water, restart and draw sense high level for Kaiba. Draw sense light, lp boost both types, draw sense earth and draw sense spell trap for odion. Draw sense wind, hhg and lp boost for Mai. I wasn't farming but just levelling up a few characters. Now trying Yami to see if I can get destiny draw.
Great! I also got Restart for Kaiba during the Yami Marik event. I'm just glad that they give gems for the skills you already have if you get them again. I've lost count of how many times Aster got the life point boost B skill. XD
