Drop Rates: Difference between revisions

Created page with "This page explains how item drops work on MuhRO: the server rates, the Low Rate Drop Boost, drop gear, drop buffs and the KS penalty - and how they all combine. == The short version == * Base rates are 25x (items/equips), 50x (cards) and 4x (MVP cards), with logarithmic scaling: the rarer the item, the more of the multiplier it gets. * Normal cards are capped at 0.2%, MVP cards at 0.04% (before buffs). * Playing at reduced EXP rates gives a permanent personal drop boos..."

MuhRO has kill-steal protection: enable it with <code>@noks</code> (also <code>@noks party</code> / <code>@noks guild</code>). While you are fighting a monster, other players' attacks on it are blocked for ~15 seconds at a time.

KS protection does not apply to: MVPs and their slaves, monsters near an MVP, PvP/GvG maps, Happy Hour maps and owners who are idle/AFK.

A weapon with an official 0.05% drop rate:


* Server rate (25x, logarithmic): 0.93% - this is what everyone gets.
* Server rate (25x, logarithmic): 0.92% - this is what everyone gets.
* You play 1x rates at Base Lv 250 (+50% boost): 1.33%.
* You play 1x rates at Base Lv 250 (+50% boost): 1.34%. Note this is not simply 0.92% x 1.5: the boost raises the raw multiplier from 25x to 37.5x and the logarithmic curve then compresses that, so the realized gain here is about +46%. On rarer items more of the boost comes through (a 0.01% item goes from 0.25% to 0.38%, the full +50%).
* You wear +10% drop gear, chew an HE Bubble Gum (+200%) and it's Happy Hour (+50%): total bonus 360%, so 1.33% x 3.6 = ~4.8%.
* You wear +10% drop gear, chew an HE Bubble Gum (+200%) and it's Happy Hour (+50%): total bonus 360%, so 1.34% x 3.6 = ~4.8%.


That's roughly a 1-in-21 chance instead of the official 1-in-2000.

=== Worked example: common item (5% base) ===
The same player hunting an item with an official 5% drop rate:
* Server rate (25x, logarithmic): 26.5%. The effective multiplier is only about 5.3x - common items get far less of the 25x than rare ones.
* Low Rate Drop Boost (+50% headline): 32.7%. The curve compresses it even harder here - the realized gain is only about +23%.
* Same buffs as above (total bonus 360%): 32.7% x 3.6 = 117.6%, which slams into the 90% cap - final chance 90%.
So for common items, buffs quickly stop mattering: anything that would land above 90% is simply 90%.

== Checking rates in game ==
<code>@mobinfo <monster name or ID></code> (short: <code>@mi</code>) lists a monster's drops with their rates. What the numbers mean depends on your display mode, which you set with <code>@mobinfomode</code>:
{| class="wikitable"
! Command !! What @mobinfo shows
|-
| <code>@mobinfomode base</code> || Server rates - after the server multiplier and the card caps, before any personal modifiers. The same for everyone. This is the default.
|-
| <code>@mobinfomode personal</code> || Your effective rates - includes your Low Rate Drop Boost, drop gear, active drop buffs, Happy Hour (if you are standing on a boosted map), any KS penalty and the 90% cap.
|-
| <code>@mobinfomode default</code> || Back to the server default (base).
|}
Notes:
* <code>@mobinfomode</code> without an argument simply toggles between base and personal.
* The setting is saved per character and survives logout.
* Personal mode is a live preview of the formula on this page: change gear, lose a buff or leave the Happy Hour map and the numbers change with you.
* <code>@mobinforate</code> is the same command under another name.
