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

v1.2.0
• 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.
