As the title says deidara's attacks seem to be earth atribute but its not mentioned. Don't know if its a bug or its a tooltip issue.
Was doing Ninja Exam 96 with the earth puppet and deidara's normal attacks seemed to do damage, however,other earth ninjas like mifune who have nin/tai on basic attack like deidara had no effect on the puppet.

Is something missing, is this intentional or its a bug?
Need some enlightment
