> To determine the level at which you reach half the experience points (XP) of the maximum level in RuneScape, we need to look at the experience table provided in the book.

The maximum level in RuneScape is 99. According to the experience table, the experience required to reach level 99 is 13,034,431 XP.

Half of this experience is:

13,034,431 XP / 2 = 6,517,215.5 XP

Looking at the experience table, the level that requires just over 6,517,215 XP is level 85. The experience required to reach level 85 is 5,902,831 XP, and the experience required to reach level 86 is 6,517,253 XP.

Therefore, you reach half the experience points of the maximum level at level 85.
