Patch & Balance Comparison
The meta changes. Be first. Track every stat shift, hidden buff, and silent nerf across hero kits and item trees — patch by patch.
How It Works
Compare any two patches in seconds
Patchly's comparison engine indexes every numerical change across hero abilities, item stats, and map constants. Select two patch versions, pick your heroes and items, and get a clean diff you can actually read.
1. Pick Two Versions
Choose from the full version history — 7.32e through 7.37c. The tool locks both snapshots and pulls their raw stat tables from Patchly's database of 4,200+ tracked entries.
2. Filter by Heroes & Items
Search for specific heroes like Invoker, Meepo, or Phantom Assassin. Toggle item comparisons — Black King Bar, Blink Dagger, Aghanim's Scepter — or let the engine scan everything.
3. Read the Diff
Every change is color-coded: green for buffs, red for nerfs, yellow for hidden adjustments (mana cost shifts, cooldown tweaks, radius changes). Export to CSV or share a permalink.
Real-World Examples
What players catch with the comparison tool
These are actual comparisons our users ran in the last 30 days — from spotting silent buffs to confirming suspected bugs.
Phantom Assassin — Crippling Fear Duration
Between patches 7.35a and 7.36b, PA's Crippling Fear stun duration was quietly reduced from 1.4s to 1.2s at max level. The patch notes listed only "Talent tree adjustments." Our diff flagged it immediately. 12,847 views.
Invoker — Quas/Wex Refresh Rate
A user comparing 7.34d → 7.35c discovered that Invoker's Orb Refresh cooldown was changed from 10s to 8s — a 20% increase in Wex spam potential. Community confirmed it was intentional; the change was buried in a footnote.
Black King Bar — Duration Formula
The BKB duration formula was altered from 7.36a to 7.36b: the intelligence coefficient dropped from 0.02 to 0.015. At 250 INT, that's 1.25 seconds less uptime. Our comparison table showed the exact delta per stat bracket.
Meepo — Earthbind Range Shift
A suspected bug: Meepo's Earthbind cast range appeared shorter in-game after 7.37a. Comparison revealed the range was indeed reduced from 600 to 550 — a silent nerf not mentioned in the developer blog. Thread reached 3,100 comments.
Aghanim's Scepter — Anti-Mage Mana Burn
After 7.36b, Anti-Mage's Scepter upgrade (Mana Break on Blink) showed inconsistent damage. The diff confirmed the damage formula was changed from 10/20/30/40 to 15/25/35/45 per stack — a net buff masked by a wording change.
Blink Dagger — Cooldown Increase
Between 7.33c and 7.34a, Blink Dagger's cooldown was increased from 18s to 20s. Combined with the 7.34b price bump to 2,250 gold, our users calculated a 14% net mobility nerf for dagger-reliant heroes like Pudge and Tidehunter.
Why Use It
Built for players who read beyond the headlines
Patch notes tell you what changed. The comparison tool tells you what it means.
Catch Silent Adjustments
Developers often tuck minor stat tweaks into talent reworks or general balance sections. Our engine tracks every single numerical field — no change slips through.
Verify Bug Reports
When the community reports "this hero feels weaker," run a comparison. You'll see within seconds whether a stat was actually changed or if it's psychological.
Build Meta Predictions
Team analysts and content creators use Patchly diffs to forecast which heroes will climb the win-rate ladder before the first ranked game of the new patch.
