Acheron Guardian

Most encounters have a ceiling of three physical items, not a mandatory package size. Zaikan has one approved exception: a 2% three-talisman bonus can raise its total to four items. Most early invasions give one item; middle encounters use two slots and selected advanced encounters can use three. Most bosses and elites give one Primary reward and two distinct bonuses. Kundun guarantees 3 Ancient Boxes, Selupan drops a Socket Box or Darkangel armor, and Medusa guarantees a Bloodangel Weapon Box (14:157). Other encounters follow Ruud Shop progression. Soul and Anvil are split across related encounters. Temple Guard and Imperial drop reinforcement materials only; their Soul, Anvil and Moru remain shop-only, and finished gear does not drop; Fantastic Dragon retains its agreed box package. Each guide states its own package size. Fantastic Dragon retains its exact box package; Elemental Monkey gives three unstackable Mithrils. Events use their separate completion packages. Participation Ruud is paid directly; Ruud boxes are chance bonuses. Jewel bundles are additional chance drops, never a replacement for the primary reward. Primary boss loot has no level/reset gate; native access and equipment requirements still apply. Rare bonuses retain their displayed eligibility. Shared Ruud is the total pool, not the amount paid to each participant. Boss item tiers do not block participation Ruud; event bonus tiers apply to the whole additional reward.

No encounters match that search.

Participation Ruud

400 shared pool

One shared pool for the successful Guardian encounter, among active eligible participants. Each eligible completion gives one personal or shared package according to the event rule above. Use the highest reward tier you meet; tier packages are alternatives, not cumulative.

Activity: At least 70% active combat time. Damage, tanking and recent support skills near an engaged party count; movement alone does not.

Claim limit: Two rewarded completions per account per day.

Reward tier P2 — Level 800+ / 5 resets

Only your highest eligible tier package is awarded. Packages do not stack.

Guaranteed drops

Each group gives one outcome on every kill or eligible completion. Alternatives share the group; they do not all drop together.
