As for when you should use a Seal... use Master Seals on non-promoted classes at level 10 to upgrade them, and Second Seals on non-promoted classes at 10 to switch them over to another class tree (mostly worthless, though switching characters that have access to Mercenary, such as the Avatar, over to it ASAP is generally a good idea), or to switch a promoted class into another promoted class at level 15.
1 The maximum that can be used on a single enchantment is 30 levels, while the anvil will accept jobs up to level 39 (in creative mode the anvil limit is lifted). 2  Level 16 is a quarter of the way to level 30, while level 22 is about halfway there.3  Level 30 in turn, is halfway to level 39. Maximum experience value can be gained by /xp command is 2147483648 (which is 2^31. 2  Likely a limitation due to the 32 bit nature of Minecraft.). 3  Maximum level is 21863, but you can get more level using command,in this case the experience bar may disappear and reappear.
