Star Point

Star Points are special points Mario can accumulate in the games Paper Mario and Paper Mario: The Thousand-Year Door. They are earned for battling and defeating enemies. When Mario collects 100 Star Points, he gets to level up his HP, FP or BP. Mario can't get more than 100 Star Points per battle. Essentially, Star Points function as Experience Points.

In Paper Mario, Mario can level up enough so that weak enemies will not give him Star Points upon their defeat, and once he reaches level 27, he will not receive any more Star Points at all. He will, however, still receive the usual coin rewards as well as hearts and flowers.

In Paper Mario: The Thousand-Year Door, Mario will be awarded a minimum of one Star Point at the end of the battle, no matter how weak the enemies are compared to his level. Additionally, Mario can automatically defeat enemies who no longer give more than 1 Star Point by using certain badges, though he will not receive any star points or coins if he defeats them in this way, and these badges do not work in the Pit of 100 Trials. Mario still cannot level up beyond level 99 in this game under any circumstance.

Amazy Dayzees are worth a high amount of Star Points if Mario can defeat one before it flees. The amount varies on Mario's current level, however, it will decrease as Mario levels up more.

Trivia

 * In the first three Paper Mario games, each game's incarnation of Merlon bears a pendant that resembles a Star Point.
