All monsters, including MvPs and other bosses, are free for all, so kill-stealing is allowed in ExperienceRO.

Berzebub Card Card reduces casting time by 30%. 4 Berzebub Cards should completely reduce casting time (not to be confused with after-cast delay which is from Card Kiel D-01 Card).

Although 850 DEX can provide instant casting for skills, some skills are modified to still have casting times, namely Double Casting and Tracking.

Beelzebub, which can be found in the MvP room Bossnia, drops its MvP card at a 10.00% rate. Berzebub Card Card can also be won from Jackpot.
