What is the pro build for Kassadin in patch 26.21?

The most-recent pro Kassadin build is shown at the top of this page — full item order, runes, skill order and summoner spells from a tracked professional player's solo queue game.

Which pros play Kassadin the most?

ggez.gg tracks all major-region pros (LCK, LEC, LCS, LPL, LTA, VCS) and surfaces every recent solo queue Kassadin game with the player's name and team logo.

Are these Kassadin pro builds from solo queue or competitive?

Solo queue — every entry comes from a Riot match-v5 record on a verified pro player's account, not stage play. That keeps the build data current with patch 26.21.

How often are Kassadin pro builds updated?

New pro Kassadin games are ingested every few minutes and the list refreshes automatically.

Can I see the runes and skill order for each Kassadin pro build?

Yes — expanding any entry shows the full rune tree, skill order (Q/W/E/R points-per-level), summoner spells, item order with timestamps and final stats.
