Tribute Summon

Any monster of level 5 or higher requires a Tribute Summon (Sacrifice Summon in the Japanese, soon to be changed to Advanced Summon). Monsters that are Level 5 or 6 require one monster to Tributed (soon to be called Release), while monsters of Level 7 or higher require 2 monsters to be Tributed. Some high-level monsters (such as "Moisture Creature") require 3 monsters to be Tributed in order to activate an effect.

Cards like "Mausoleum of the Emperor" can bend the rules of Tribute Summoning by allowing you to pay Life Points instead of Tributing monsters. However, this means the Summon is then considered a Normal Summon and not a Tribute Summon.

Even if the monster is Tribute Set instead of Tribute Summoned, the correct number of Tributes must be offered. So you cannot Set a monster in order to avoid offering a Tribute.

A Tribute Summon is treated exactly as Normal Summon, except a few cards refer specifically to whether or not the card was Tribute Summoned (such as Monarchs). Normally only one Tribute Summon can be conducted in the same turn (exceptions: see "Ultimate Offering" and "Double Summon"). This means you cannot Normal Summon or Set a low Level monster and then Tribute it immediately to Tribute Summon a high Level monster.

Tributing a monster for a Tribute Summon is not considered a Cost. However, similar to paying costs, players cannot respond immediately to the Tribute of a monster, since Tributing does not have a Spell Speed. If the Tribute Summon of the new monster is negated, however, the Tributed monster will not return to the field.
