TierFill — PoE2 Trade Tier Filter by Sknow

TierFill adds a small tier picker to each stat-filter row on the Path of Exile 2 trade site. Instead of looking up numeric breakpoints and typing them in, you pick a mod the normal way, choose a tier (e.g. T1), and TierFill fills the correct minimum value for you.

Features:
• Per-row tier picker — a compact "≈ TIER" control appears left of the MIN box on stat rows it has data for. Pick a tier; it fills the computed minimum.
• Handles averaged flat-damage mods (Adds X to Y) automatically — these are filtered against the average of the two rolls, and TierFill does the math.
• Inclusive / Strict modes — Inclusive never misses a tier; Strict only keeps results genuinely at the tier or better.
• Result tier badges — each searched mod on a result is annotated with its tier and roll quality, so you can see at a glance which results hit your target.
• Stays out of the way — it only fills the native inputs and lets the site run the search. It never automates searches or contacts Grinding Gear Games' servers.

Scope: TierFill works on explicit stat mods (the prefixes/suffixes that roll on weapons, armour, and jewellery). It does not add a picker for pseudo mods, implicit/rune/crafted/enchant mods, or mods on items outside that scope such as tablets — those rows are left as the trade site's normal number boxes.

TierFill collects no data and makes no network requests — everything runs locally in your browser. Open source (MIT): https://github.com/Sknoww/tierfill

Changelog

v1.2.1
• Fixed scrambled tier numbers on several ladders where PoE2DB had mixed in
tiers belonging to other item bases. Affected "Level of all Spell Skills"
and "Level of all Minion Skills", the Remnants collection range, and Belt
mana regeneration — these now show the correct tiers in the right order.

v1.2.0
• Rebuilt every mod's tier data directly from PoE2DB. Many weapon mods had been
showing values that were too low — most noticeably caster staves, which were
sharing the wand tiers for Spell Damage, Critical Spell Damage Bonus, Gain #%
of Damage as Extra Fire/Cold/Lightning, and maximum Mana. Those now use the
correct (higher) staff tiers.
• Around 230 more mods now have a tier picker and result badges.
• Corrected an over-inflated Block ladder, removed some phantom tiers, and fixed
understated charm recovery.

v1.1.1
• Bows and crossbows now use their own added-damage tiers for "Adds # to #"
Physical / Fire / Cold / Lightning Damage. They had been using the lower
one-handed values, so tier picks filled minimums that were too low — now
corrected tier-for-tier from PoE2DB.

v1.1.0
• Life and Mana flask mods now get a tier picker and result badges.
• Jewels: set a minimum by roll percentile (Min / 25% / 50% / 75% / 90% / Max);
results show how high each roll sits in its range.
• Item-type selector is now a labelled dropdown (One-Handed, Caster, Jewellery, …).
• "Increased Rarity of Items found": corrected tier data and a combined,
item-type-aware prefix+suffix ladder.

v1.0.2
• Tier picker and badges now work on desecrated and fractured mods.
• Added the deflection mod "Gain Deflection Rating equal to #% of Evasion Rating".
• "Increased Rarity of Items found" ladders labelled by prefix/suffix, with live
item-type re-resolution when you change the item category or base.

v1.0.1
• Firefox submission fixes: declared no data collection and switched to safe DOM
building (no innerHTML).

v1.0.0
• Initial release — filter PoE2 trade stat mods by tier instead of raw numbers,
with a per-row tier picker that fills the computed MIN value.
