The table above shows how all the skills available to Thieves and Assassins relate to each other. Anything in the light blue section can be gained as an Thief, while anything in the dark blue section must wait until Assassin has been achieved. The red numbers just to the right of each skill icon indicate the maximum possible level for each skill. The lines, arrows and black numbers show the relationships between skills. For example, the line from Steal with an arrow pointing at Hiding and a black number 5 next to it shows that Hiding requires 5 levels of the Steal skill to become available.

The meaning of the coloured text is as follows:
Green Text: Passive Skills (does not use sp, always in effect)
Blue Text: Active Skills (uses sp to activate)
Purple Text: Offensive Skills (uses sp to activate and always provokes monsters that it affects)
