Methodology

New page

Possible candidates for Zone Zero ...

=Summary=
Currently the top contenders (all of which have a 6:40 respawn) are:
* [[South Qeynos]] - 32 different levels, but only 41, 45, and 50 at the high-end (40+)
** Presumably [[North Qeynos]] has the same ZEM; if so this would add four more levels for a total of 36 (unfortunately all lower ones): 12, 31, 33, 30
* [[Lake Rathe]] - 28 different levels, but with a better high-end distribution: three 40's (40, 48, and 49) and three 50's (51, 55, 59)
* [[Freeport]] - while they are technically three separate zones, collectively the Freeport zones have 39 levels between them ... however (like Qeynos) there are no 51+ mobs

Other close contenders include:

* [[Paineel]] - 22
* [[West Karana]] - 24
* [[Highpass Hold]] - 25
* [[Greater Faydark]] - 25
* [[Lesser Faydark]] - 27
* [[Ak'Anon]] - 29
* [[Swamp of No Hope]] - 29

=Detailed Evaluations=

== South Qeynos ==

32 different levels of mobs and a short respawn timer (6:40) make South [[Qeynos]] a very attractive option. The one main downside is that there's only a single level 50 mob, and none 51+.

'''NOTE:''' We could test and confirm that South Qeynos and North Qeynos share a ZEM ... but North Qeynos also lacks any 51+ mobs, so this doesn't really help.

== Lake Rathe ==

Perhaps the best contender to South Qeynos. It has the same respawn time (6:40), and while it has 4 levels less than SQ (28 vs. 32), those levels are better distributed at the high end, with three 40's (40, 48, and 49) and three 50's (51, 55, 59).

However, presumably all three zones share the same ZEM. If this is true, then together they offer a total of 38 levels:

<pre>

== Lesser Faydark ==

[[Lesser Faydark]] has the same respawn timer as South Qeynos (6:40), but fewer levels (27 vs. 32), and only two level 40-something mobs (vs. SQ's 3). However it has both a 50 and a 51 (South Qeynos only has a 50), so it's slightly more friendly for higher levels.

== Methodology ==

To count the levels I wrote a quick Javascript script:

<pre>
const npcsTable = $('table:has(.headerSort:contains("NPC Name")):has(.headerSort:contains("Level"))')[0];
if (!npcsTable) {
alert('No NPCs table found; are you on a zone page?');
throw new Error('No NPCs table');
}

const rows = Array.from(npcsTable.querySelector("tbody").children);

const mobs = rows.map((tr) => [
tr.children[0].innerText.trim(),
tr.children[2].innerText.trim(),
tr.children[3].innerHTML.trim().replace(/\[.*?\]/gi, ""),
]);

const staticLevelMobs = mobs.filter(
([name, eqClass, level]) => eqClass.trim().toLowerCase() !== 'merchant' &&
!level.includes("-") && !isNaN(level)
);

const staticMap = staticLevelMobs.reduce((mobs, [name, eqClass, level]) => {
mobs[level] ||= [];
mobs[level].push(name);
return mobs;
}, {});

const mapString = Object.keys(staticMap).reduce((mapStringInProgress, name) => {
return (
mapStringInProgress +
` "${name}": ${JSON.stringify(staticMap[name])},` +
"\n"
);
}, Object.keys(staticMap).length + " levels found:\n");

console.log(mapString);
</pre>

To use it, opens your browser's "Developer Tools" by pressing F12 (while on a zone page). Then, paste the code above into the "Console" and hit enter.

=== Alternate Version ===

For those who want to use the above script, but want to include non-fixed level mobs, try this version instead:

<pre>
const npcsTable = $('table:has(.headerSort:contains("NPC Name")):has(.headerSort:contains("Level"))')[0];
if (!npcsTable) {
alert('No NPCs table found; are you on a zone page?');
throw new Error('No NPCs table');
}

const rows = Array.from(npcsTable.querySelector("tbody").children);

const mobs = rows.map(tr => [
tr.children[0].innerText.trim(),
tr.children[2].innerText.trim(),
tr.children[3].innerHTML.trim().replace(/\[.*?\]/gi, ""),
]);

const mobsWithLevels = mobs.filter(
([name, eqClass, level]) =>
eqClass.trim().toLowerCase() !== 'merchant' && (
(!isNaN(level) && level < 60) || // Mob has a simple numeric level (eg. 5)
level.split('-') // Mob has a level range (eg. 5-10)
.map(x => {
const numericLevel = Number(x.trim());
return !isNaN(numericLevel) && numericLevel < 60;
})
.reduce((memo, bool) => memo && bool)
)
