Multikill & Combo Kill
Grouped defeats and sustained hunting award separate EXP bonuses.
Multikill
Defeating at least three monsters together grants bonus EXP. The bonus grows from 1% at three kills to 4.5% at ten or more.
Combo Kill
Continued hunting builds a combo, with an EXP orb appearing every 50 counts. Combo progress follows the number of skills used to defeat monsters rather than the raw monster total, and caps at 9,999.
Higher combo bands create more valuable orbs: their EXP ranges from 500% of a normal monster's base EXP at early counts to 1,100% from 2,000 onward.
Collecting orbs
Orbs are visible only to the character who earned them and must be touched within one minute. Combos briefly survive map changes; after Bounty Hunter or Inferno Wolf content, the return grace period lasts up to 20 seconds.
