Level 11

Level 11 monsters are monsters who have eleven red stars near the top of their card. This is the highest level allowed for Tuner Monsters in the game, for obvious reasons.

Level 11 monsters require two Tributes in order to be Normal Summoned (known as Tribute Summoned). However, there is currently only one Level 11 monster in HCCG, Blood Tear the Final Trinity, and it is a Synchro monster. Their stats may vary, but generally fall in between the 2500-4000 range.
